e-Cart2
UL Listing Do’s and Don’ts
Question # 1
FRAME:
Listed e-Cart Jrs must all be built on the aluminum frame.
This frame is NOT required to be powder coated.
The standard hand truck construction is NOT acceptable.
Stainless Steel would be acceptable.
Listed e-Carts must be built on the “4 wheel” steel frame (G90 coating). No
visible change from before.
Any other sheet metal, plates, or other ferrous metal on the cart needs to be
powder coated with one of the approved paints on the list.
Paint certifications are required for all of it.
Other custom designs are not Listed. Customer specific designs of frames are
not Listed.
THE UL MARK LABEL:
The listing label is a purchased UL serialized label affixed to the nameplate.
We have UL in the USA only. We are tested to UL1640 for Construction Site Use.
No Canadian certification at this time. Canada has no such reciprocal standard
providing general coverage. Specific model-by-model coverage is available in
Canada per CSA C22.2 No. 105. “General Use Power Supplies”.
Lot blessings by CSA, QPS, etc are available on a per-lot basis.
Also, each cart is required to have a voltage and current rating, and this rating
must be marked on the cart. We use engraved metal plates riveted to the unit.
All other materials in both carts are to be listed and suitable for outdoor use.
Wire, cable, conduit, conduit fittings, crimps, hole plugs, ground & neutral bars,
essentially everything except hardware.
UL Listing Do’s and Don’ts
Question # 2
Question # 3
Max transformer & kVA for Ecart Jr is 15kVA, same voltage ratings.
Transformer must have an outdoor-acceptable rating such as NEMA 3, 3R, 3S,
4, 4X, 6, or 6P.
Secondary Panel:
All receptacles are required to have a spring closing or gravity closing
weatherproof covers.
The “COMBO” enclosure rain lid covers everything under the rain flip cover.
Other receptacles need to have rain flip covers, including camloks.
The only typical construction that is not permitted is hanging pigtail
connectors. Hanging pigtail connectors are 1) prohibited by the standard, and
2) have no self closing flip lids. This removes the PL / PM series of e-cart Jrs.
Secondary main breaker is permitted, optional.
Appropriate secondary breakers must be provided on all secondary
receptacles. Branch Circuit protection per NEC.
Secondary receptacles must be Listed and weather protected. They may be
mounted on a panel if of suitable type or may be mounted within any
enclosure on the cart, such as the “Combo”, or within the transformer, edge of
panelboard, dedicated enclosure, etc.
GFCI breaker, GFCI receptacle, or 1075-style GFCI must be provided for all
125V 15, 20 & 30A receptacles. ALL other receptacles that are not GFCI
protected must be marked “Not GFCI protected”.
Open neutral protection GFI is not required on e-Carts because the entire
system through the isolation transformer is controlled. No chance of a lifted
neutral wire from the transformer (unless tampered with).
UL Listing Do’s and Don’ts
Question # 4
All listed EC2s and Jrs must have either an inlet blunt pigtail or an inlet
connector such as in IEC inlet, CS inlet, or Camlok panel.
6ft is standard – custom lengths are acceptable.
It is no longer permitted to have "wired by customer" type connection.
If the pigtail is provided, the plug on the end is optional.
A main AC switch is required. It can be a fused disconnect, a separate
molded case breaker in a box, or a main breaker installed in a 480V panel.
A primary side 480v panelboard is permitted, optional.
Primary side 480 Volt receptacles are permitted, optional, must be Listed,
rain protected as described above. Must be breaker protected. Must be
marked “Not GFCI Protected”. Not much room for that on the e-Cart Jr.
All 10” dia wheels and standard legs are permitted.

5 Easy Steps to Temp Power
How to determine the right Temp Power Product
Step 1 – Determine the NEED
( Distribute or Transform)
Step 2 – Determine the AVAILABLE POWER
- Volts Amps Phase
Step 3 – Determine the
EXPECTED ELECTRICAL OUTPUT
Step 4 – Determine the CONNECTIONS
How will they connect in and out ?
Be specific
Use NEMA values (ie L5-20)
Volts amps phase expected
Step 5 – Determine the BUDGET

OSHA & Smartmonitor™
Assured Equipment Ground Continuity Program
CFR 29 1926.404
OSHA Letter dtd 12/1/1991 allows the use of
“GCM” type devices to aid with the Assured
Equipment Ground Continuity Program.
“…This is in response to your September 5 facsimile of a letter dated
March 25 concerning the use of the Ericson Manufacturing Company's ground
continuity monitoring device.
In regard to your question whether ground continuity monitoring devices
provide compliance with 29 CFR 1926.404(b)(1)(iii)(D), (E), and (G),
please be advised as follows: These provisions require that (1) all cord
sets and receptacles that are not a part of permanent wiring, and cord and
plug-connected equipment required to be grounded must have all equipment
grounding conductors tested for continuity and each receptacle and
attachment cap or plug must be tested for correct attachment of equipment
grounding conductor; (2) the tests be performed on a periodic basis; and
(3) the tests be recorded.
A ground continuity tester permanently wired to a cord set's receptacle
can be used to comply with the requirements to test the cord to which it
is wired (1926.404(b)(1)(iii)(D) and (E)). This is based on the assumption
that all cord connectors used on the site would incorporate the tester or
would otherwise be tested in compliance with the ground-fault protection
standard…”
“…The employer would have to ensure that cord sets identified by the
device as having a defective grounding conductor are immediately removed
from service…”
