If you are asked to extend a circuit and the Zs is already too high, what can you do.

Can you extend the circuit safely?

Or maybe the reading is just in limits, but the new extended cable will take the Zs over the permitted maximum.

Can you still do the work.

In this video we will look at this problem and offer a reliable and correct solution for carrying out the work.

Confirming that Zs does not exceed the acceptable and permitted maximum value according to the Wiring Regulations is an important test that should always be carried out after any electrical work.

The safety of the occupants of the building may be compromised if the Zs is too high.
