Seaward has introduced an adaptor to
extend the range of electrical safety
tests that can be carried out on 3-phase
equipment.

The Seaward TPA test adaptor
allows the electronic control circuitry
in specialist factory, industrial and
workshop equipment to be included as
part of in-service inspection and testing
protocols.

The TPA unit is available with 16A
or IEC 60309/ BS4343 compatible
plugs and sockets allowing it to be
connected in-line with the 3-phase
supply to measure the current flowing
in the protective conductor.

It has been developed for use with
the PrimeTest 250 PAT and extends the
range of measurements that can be
performed on 3-phase equipment
using a handheld tester. The TPA and
Primetest 250 form part of a range of
portable appliance testers and
accessories that meet workplace
electrical safety testing needs.
