Claw hammer
Used for removing cable clips, nails etc.
Useful for lifting floor boards, cable clipping and general fixing tasks
For safe use ensure that grip is tight, head is not damaged and kept
away from any electrical supplies including battery terminals, goggles
must be worn when used on bricks or masonry work.
Club hammer
Used mainly for chasing masonry walls, googles must be worn
Used with a cold chisel or bolster for heavy work.
Large hack saw
Used for cutting steel conduit, usually 32 teeth per inch, general cutting tool used
for metal work, fully adjustable to enable quick blade removal/replacement, for
safe use ensure that hands are kept clear when cutting, grease/ oil is removed
from handle and frame, before use make sure locking screw is tightened and
cutting teeth are positioned correctly, cutting should be at a 30 degree angle to
assist with straightness.
Junior hack saw
Mainly used when installing plastic conduit, fine cutting work, very
flexible blade, can be used as a guide when preparing steel wire
armoured cable.
Knife
Used for cutting cable sheath, many electricians, when second fixing
twin and earth cables, pull the CPC to strip this type of cable, this can
cause the CPC to become extruded and decrease in size.
It is recommended that this cable should be stripped using a knife.
A good quality knife is a must when preparing steel wire armoured cable
as the outer sheathing is thick and robust. For safety, always cut away
from you as you hold the cable.
Wood saw
Generally used to cut noggins and floorboards, a saw should be kept in
good condition, most will last a lifetime if used and maintained correctly.
Bolster
A utility tool used for chasing walls and lifting floors.
Goggles should be worn when chasing, for general maintenance, ensure
that the cutting blade is sharp and that burrs are removed from the grip
end as hands can easily become damaged.
Pad saw
A tool used to cut plaster board for the installation of fast fix boxes,
Can also be used to cut out low voltage lighting holes in plasterboard
ceilings
Cold chisel
Used to cut masonry walls, cut bricks or to fine tune chases. Should be
maintained the same as a bolster
Wood chisel
Used to chop sections of wood from whole joists, to conform with
building regulations, only a small amount should be cut to maintain
strength.
Footprint grips
Must be used to make a good connection of steel conduit, this gives
electrical continuity. If used correctly, will not leave grip marks along
the length of conduit, a must if installed on the surface of a building,
excellent grip strength, fully adjustable via screw and locking thread.
Water pump pliers (five holes)
Mainly used as a tool to grip nuts which connect trunking sections.
As these are adjustable in five positions, these are also used to
gain a good grip on SWA glands.
Draw tape
Used to install single core cables through conduit sections.
Cable ends should be staggered to allow for ease of installation,
insulating tape should be used to cover join between cables and
draw tape, eye end is pushed through conduit, good practice is to
double twist stripped cable ends allowing for push or pull through
awkward sections.
Insulation tape
Available in many colours, used to cover live connections, can be used
to mark cables as identified line, neutral etc, brown tape can be used to
identify switch line in three plate lighting.
Drill bits
These tools have been designed for drilling holes into building structure
The type of drill bit should only be used for drilling into the material it
was designed for; goggles must be worn when drilling. For correct depth,
use insulating tape to mark drill for correct depth for rawplug.
Masonry bit
Steel bit
wood bit hole cutter
Stocks and dies
A tool used for threading steel conduit, threads are cut by turning the
stocks by hand, care must be taken to remove swarf during the cut,
turning the stock backwards will prevent build up.
Tallow or cutting grease must be applied once the initial cutting of the
thread has begun, a rag is used to remove excess lubricant.
There are generally two types of thread, half socket, and runner. In
general a half socket is three threads after the end of the die, while the
runner thread is a coupler plus a lock ring, a reamer is used after the
threads have been made, this cleans the inside of the conduit.
Vice and bender
This tool is used to cut, bend and thread steel conduit on site.
Conduit should be cut using the vice, take care when using the hacksaw,
the cutting angle of the vice enables the electrician to achieve an
accurate cut, this leaves a good angle for the stocks and dies to be
pushed and turned onto the conduit which is threaded.
The formers on the machine are used to bend the conduit into thirty
degree and forty five degree sets, ninety degree right angle bends are
easily formed, short length threading is also carried out by using the
locking pins on the frame, joining and tightening of couplers and conduit
boxes must be carried out by using the vice.
Battery drill
A general purpose tool, used for drilling without the need for a supply,
especially useful when installing new consumer units if the supply has
been isolated, where both fixing and the use of a screwdriver bit are
needed.
Excellent for multi fixing of cable clips when using FP200 and similar
cable types, usually comes with a charger unit and double battery.
Modern types of drill allow for hammer drilling along with torque
adjustment for removal or installation of stubborn screws.
Twist drill insertion enables quick change from drill to screwdriver bit
Reverse button is used to remove screws and speed is controlled via
collar mechanism, right angle chuck pieces allow for close drilling into
trunking etc.
Hole cutters
Every electrician should have a set of hole cutters, these are used so
often that a good quality set of regular sizes- 20mm and 25mm
Are worth the investment, time saving and good quality workmanship
are essential part of the trade, goggles must be worn when cutting into
steel, never drill above without using some form of covering to the arms
and face, hot steel falling onto the skin will lead to accidents.
Used mainly when installing both steel and plastic conduit, ensure that
removed material is taken out of the cutter, the cutting blade should not
have broken teeth and the drill bit holder known as a mandrill has a
screw which should be tightened before use, when cutting into thick
material the use of cutting lubricant is essential.
Pliers
A tool with many uses, is used for gripping objects which are being cut
or removed from structures, can be used to cut cables, good at removal
of plastic pattress cable entries.
Will aid any gripping action, especially when pulling cables into conduit
using a draw tape.
Used for removal and installation of trunking nuts and bolts.
Side cutters
A tool used for cutting and marking cables during installation.
Most electricians will rely upon this tool to second fix, excellent for
removal of insulation from cable cores, cables can be marked by
crimping cores to indicate switch lines etc.
Crimping tool
A tool used to terminate crimp lugs onto cable ends,
Adjustable crimp holes are used to terminate different sizes of lug, usually 1.5mm, 2.5mm and
4mm lug sizes on standard tools.
For larger sizes, hydraulic crimping tools are used to ensure a good,solid terminal end that can
be bolted onto busbars etc.
Bending spring
Available in different sizes for standard plastic conduit diameters.
Springs are usually adapted for removal by twisting a length of single core
cable to eye end.
Springs must be used carefully, make sure that bends are in centre of conduit
and that support is provided during this procedure, use the top of the knee to
gain initial bend, then pull slowly until right angle bend is gained, rubbing the
conduit will aid this process.
Screwdrivers
The essential fixing tool, various shapes and sizes, always use the correct type and size to fit the
required screw.
The most unusual types are used for difficult acces or for security.
Terminal screwdriver
A second fixing tool for gaining access to small screws in switches,
ceiling roses and other installed accessories.
These tools should never be used for working on live circuits, the use of
the terminal neon type screwdriver can be especially dangerous as it
can become live when touching the end plate if the resistor is defective.
Flat file
This tool is generally used after cutting uni-strut or other large
metal fixings. Trunking and tray work will require sharp edges to be
filed after cutting and joining, this is carried out so that cable
insulation is not damaged by rough metal surfaces.
Reamer
When cutting and threading steel conduit, small waste gathers along the cutting edge,
often getting into the inside of the conduit.
This will decrease the space available inside the conduit for cable installation, there will
also be a sharp edge to the conduit after cutting and threading has taken place, using a
reamer removes debris and sharp edges.
Long nose pliers
This tool is used to grip and push or hold cables in place so that a good
termination can be made, used mainly to guide or for accuracy.
Bush key
This enables male bushes to be tightened where couplers are used to join conduit into boxes or
trunking. Good fixing of conduit is essebtial to maimtain earth continuity, remember conduit is
a good conductor and must have earth continuity for safety.
Rotary MIMS stripping tool
A specialist cable tool, adjustable to fit all sizes, cutting blade can be
changed using screw grip, turn for desired length then hold pliers behind
for square cut.
Compression tool
This tool is used to seal MIMS pot by compressing brass pot to plastic
seal which has been filled with insulating compound, the tool has three
small teeth which compress the brass pot to the seal. Must be cleaned
after use.
Potting tool
A tool designed to attach the MIMS pot to the cable, it is screwed onto
the gland thread, steady, regular push and turn will screw the pot onto
the cable, do not overturn the thread down the cable, stop when cable
reaches pot inner length.
Spirado
A pump action draw tape, flexible steel design, strong enough to pass conduit bends easily and
provides enough power to push debris out while pulling in cables.
Multi-meter
A meter used for measuring ohms, volts and amperes. Also used for
diodes, farads and continuity using audio signal.
Continuity/insulation meter
Designed to meet 17th edition wiring regulations and GS38, used to test
MIMS cable before installation, will test continuity of circuits and give
values of insulation resistance at 500V, CARE MUST BE TAKEN WHEN
CARRYING OUT INSULATION RESISTANCE TESTS, AS THIS VOLTAGE
CAN CAUSE DAMAGE TO EQUIPMENT.
Earth fault loop tester/ RCD tester/ Clampmeter
These three testers perform live tests and must be GS38 approved
An earth fault loop tester gains values of Ze, and Zs by connecting line
to earth for the period of the test, the RCD tester sends current through
the circuit and provides a tripping time in milli- seconds, the clampmeter
is able to measure the current of a circuit by measuring the magnetic
field produced by this current, it converts this into a digital current
reading. Always check leads and body of instrument before use, check
that the calibration has been carried out and that the batteries are able
to perform the required tests, failure to do so could nullify the test
readings Causing loss of time and money, use warning signs and isolate
before testing, you must comply with EAWR 1979 before testing, safety
is your first priority.
GS38 approved voltage indicator
This is an essential part of every electrician’s toolkit.
For isolation testing, this instrument should be used as it will provide
safety, leads are to 1000V A.C, can be tested before use with proving
unit, has finger guards, only 4mm retractable tip to probes, contains in
line fused leads.
Spirit level
This tool comes in various sizes, each designed for a specific task.
Electricians commonly use a boat level as the need to ensure correct
installation of boxes, switches and sockets, this includes installing
items level and to a required height.
Insulated steps
When installing items in areas that have been energised, electricians should use insulated steps
manufactured from fibre glass or other insulated material, aluminium steps should never be
used in these areas as there is a risk of electric shock.
These steps are durable, light weight and should be checked before use that damage to rungs,
steps and screws, nuts and bolts are present, remove grease and dirt from steps, never go above
knee height of last step and refrain form leaning to far, always keep three parts holding onto
the steps and never gain height by placing steps onto another surface.
Insulation stripper
This device comes in several types, a spring loaded manual stripper and
automatic stripper. Used when second fixing and terminating
conductors, all cable sizes can be stripped by using the device as these
can be adjusted to suit.
Allen keys
Usually comes in a set enclosed in a sheath rather like a pen knife.
Essential when installing new bonding conductors to main earth terminal or when
using Henly blocks.
Tape measure
An essential device used to determine length, height and width of
objects.
Essential when measuring to scale from drawings, comes in standard
lengths and usually self retracting, never bend or crease as this will
cause the tape to wear or rip.
When using to scale – scale multiplied by length on drawing
Quantity in base unit
Example – drawing shows a socket at 6.5 cm
50 x 6.5
100
= 3.25 M on site
at a acale of 1:50
Chalk line
A retractable cord which is pulled tight between two pencil marks. This
cord is then plucked to produce straight lines across surfaces, essential
when installing conduit and trunking to building fabric.
Coloured chalk is used; this enables correct spacing of fixings and
allows visual alignment of installed equipment.
