Minor Works Cert

[carl9254]

What tests do you do on a minor works job?? I know some certs ask for different ones but my main question is if it asks for zs and the job is an extra light or something extra off a lighting circuit then do you leave zs as it will all be live??

Thanks.

You should fill in the Zs value.

If it is a light or something that is not practicable to test live than you can calculate by Zs=R1+R2+Ze

You can easily measure Ze.
Connect line to earth at one end and measure R1+R2.

This way you don't need to test live.
