Installation certificate, but can't shut down.

[Duncan Bennett]

Ho w do you complete an electrical installation circuit when you cant shut down the plant that runs on the same board?

 

[The Ghost]

Yep got confused thought he was doing EICR initially

Substitute Ze for Zdb and note on the cert. As for Ipf why could you not do that?

Not sure how you can substitute Ze for something else, it is Ze or it isn't.

LIMITATIONS!
As long as you can justify limitations on your EIC then state that shutting down for correct testing of Ze etc is not viable. If there is an up to date EICR available then you could use those readings and give the above reason for doing so.
It would depend on scope of the work you are carrying out as well, a major job would not justify limitations, but a new radial circuit from a sub-DB for example hardly justifies major disruption and cost implications when perhaps a Zdb reading with no shutdown is perfectly adequate.

I disagree Ze is a required test and there should be no Limitations as there is no provision on an EIC to introduce Limitations.

 

[GMES]

He can take a zdb reading if it's not the main incomer board and suppose he could enquire about the ze.

 

[Duncan Bennett]

Commercial premises that have had a forward thinking electrician in during a shut down usually have the useful addition of Ze and Ipf written on the incoming chamber/panel board in black marker.

You should see this place, Andy. It's been running for decades and they have not ONE certificate.

Substitute Ze for Zdb and note on the cert. As for Ipf why could you not do that?

Sintra: Yes, I can do that. I'm just being pedantic; Ze is external and you can't do that without disconnecting the main earth. And, yes, you're right about LPF. My bad!

There is no requirement to measure Ze, it can be obtained by enquiry from the DNO.
