3.7a Test an EPOD (Powerboard)
Visually inspect the appliance as per requirements
of AS/NZS3760. If the cord passes a visual
inspection proceed with the electrical tests.
AS/NZS3760 requires an earth resistance test to be
performed to each outlet.
Operators have the choice of carrying out two test
sequences for EPODs:
Procedure A: a complete test sequence is carried
out for every socket (earth, insulation and polarity)
Procedure B:. a complete test sequence is carried
out on the very last socket. Only an earth resistance
test is carried out on the remaining sockets.
Procedure A:
1. Plug powerboard lead into mains outlet socket on
the PrimeTest 125 EL.
2. Plug IEC Lead into the IEC socket on the top of
the PrimeTest 125 EL.
3. Plug the IEC Lead plug into the first socket of the
EPOD.

Note: Last socket is defined as the socket
furthest from the power lead.
3.7b Test an EPOD/Extension Lead with MOV
and/or RCDs
Visually inspect the appliance as per requirements
of AS/NZS3760. If the cord passes a visual
inspection proceed with the electrical tests.
AS/NZS3760 requires an earth resistance test to be
performed to each outlet.
This test sequence uses a leakage test to replace an
insulation test at 500V DC to avoid triggering the
MOV (surge protector) or to apply power to the RCD
to allow circuit connections.
Operators have the choice of carrying out two test
sequences for EPODs with MOV and/or RCD:
Procedure A: a complete test sequence is carried
out for every socket (earth, leakage and polarity)
Procedure B: a complete test sequence is carried
out on the very last socket. Only an earth test is
carried out on the remaining sockets.
Note: For extension leads with RCDs, follow 3.7b
Procedure A and carry out a single socket test.
