LIGHTNING PROTECTION AND EARTHING
01
General aspects of earthing and protection of equipment against lightning
damage shall be as follows :–
a.
Solid state equipment is prone to damage from lightning, therefore
equipotential bondings shall be provided for all items of equipment.
b.
The requirements for protection of structures against lightning
damage are detailed in the specification BS:6651.
c.
In all CCTV systems appreciable distances exist between the
individual pieces of equipment and between control rooms and
apparatus rooms. In these cases it is not unusual to have equipment
connected to earth via a three pin mains connector. In the event of
lightning strike, a difference of potential could occur where there is a
significant electrical resistance between the various earth terminals of
a system. With the very large currents involved, there is a strong
possibility of damage at the equipment interface.
It is therefore necessary to ensure that mains earth connections take
the shortest route, preferably via a heavy duty conductor, that
equipment cabinets are bonded together and that there is a low
resistance earth connection between the pole earth and the nearest
equipment interface, cable shall not be less than 6mm square.
d.
02
All earth connections involved in the system shall be subjected to
regular and periodic testing.
Lightning and Transient Over Voltage Protection
a
The mains supply to the new distribution board/s shall be protected
at source.
b
Protector housings shall be provided with clear front cover such
that protection indicators can be clearly seen. Housings shall be
positioned such that they are easily accessible for maintenance. All
protectors shall be bonded to a local earth supply which shall be
tested to ensure that it meets the current requirements.
c
Protectors shall conform to :-
BS6651 : 1992 Protection of structures against lightning (Appendix
C)
BS EN 60099 : 1994 Surge arrestors for low voltage installations
IEEEC62.41 Guide for surge voltages on low voltage ac power
circuits.
d
The protector shall not interfere with or restrict the systems normal
operation. It shall not :1
2

6.0
Corrupt the normal mains supply.
Break or shutdown the power supply during operation.
Have an excessive earth leakage current.
LIGHTING

7.0
System shall perform to the required standards throughout the 24 hour
periods using natural and/or existing lighting.
POWER
01
Contractor shall supply and install all cabling, Distribution Board/s, MCB's
etc. that are required for the CCTV installation.

system shall comply fully with the performance specification for the supply
voltage variations of –10% +6% and supply frequency variations of 1.5Hz
from normal. Camera voltage to be as per IEE regulations on all supplies.
03
Supply to system shall be fed from a new separate distribution board/s
installed at a convenient location to be agreed with the Head of Works, this
distribution board/s shall be supplied and installed as part of this contract.
04
Details of power supply source for the new distribution board/s shall be
given to the contractor on the site visit at tender stage. The power supply
source shall be obtained from a protected supply. i.e. supply that is fed from
the Standby Generator in the event of external supply failure.
05
