Live Tests Ecconomy 7???

[T&Earth]

Hi

I have just fitted a 2 new immersion heater elements, one of which is on a ecconomy 7 tariff
I'm going back to wire thes up & do the tests for a minor works cert. As I can not carry out a Ze & live polarity test do I use the Ze results of the stanard tarif??

Also if this work formed part of a bigger job and a full cert was need how would i carry out all the other live tests such as PEFC PSSC

An advice greatly received

Cheers
Steve

The Ze will be the same for both tarrifs as it is the same supply split at the meter. For E7 circuits test R1 + R2 as normal and calculate Zs. Note on cert that Zs has been calculated.
