Any AC current or voltage circuit connected to current or voltage transformers require a method of safely isolating the wiring from the primary plant as well as providing a means to test the relays or meters.

• IST's PK2 4-way Test Blocks have 4 poles that can be used in 3 phase current and voltage circuits.
• Routine maintenance testing can be accomplished by using GE PK2 4-way test handles. These handles or plugs are provided with studs and links so that testing can be accomplished by removing the test block cover and substituting with the properly connected test plug.
