Posted By Topic: Safety Certificate

Aug 13 2019 14:02

I was recently asked by an annoying Real Estate for a safety Certificate on a disconnection of an install.
This seems dumb to me but does anyone know if this is such a thing?

Under the ESR's this is defined as PEW (Schedule 1(1)(c)).

ESR 74A states that an ESC must be issued for PEW on an installation or part installation.

A disconnection doesn't require an ESC.
An ESC is only required on an installation or part installation once it has been reconnected to the supply.

if you have done a disconnection, then technically there is nothing left to certify, unless you made changes in the process then you have performed PEW and need to certify accordingly.

DougP, what are you basing that opinion on? Schedule 1 states that disconnections are PEW, and 74A states that PEW on an installation or part thereof requires an ESC.

Just because PEW was performed, doesn't necessarily trigger the requirement to issue an ESC.
You can carry out PEW on an isolated installation, but the ESC isn't required until the work is complete which includes being "connected or reconnected to a power supply"

"After the work referred to in subclause (1AA) is complete.."

"...the work is _complete_ only once the installation or part installation is connected or reconnected to a power supply"

"satisfied that the installation
or part installation _is connected_ to a power supply and is safe to use"

DougP's right; the trigger for issuiing an ESC is "work complete"; which is specified as "after connection". And since it's an offence to issue a cert that includes false info, issuing one that says "is connected" when what you've actually done is disconnected would be risking prosecution.

This is an(other) area of ESRs that appears to have been designed on the (mis)understanding that all work is either installing or maintaining, that it always follows a simple sequence (install: certify: (inspect): RoI: connect: ESC: liven); and that removing stuff doesn't happen. Maybe clause (2) will be amended one day to allow for completion by being permanently disconnected. But that would be admitting it doesn't match reality; and the powers that be seem to prefer twisting meanings to admitting the rules are less than perfect.

All good points but you could say that the ESC is for the live part that you disconnected from in that you havent just cut tails and left live tails from the supply. IE: you are stating that you have left the live part safe for continued use and not that the disconnected house is safe.

Any such fittings were already connected - and therefore an ESC covering that fact should have already been issued by whoever connected them.

Noting also that mandatory info on any ESC is the "date of connection", which can only be known by whoever did the connecting.

Hi, I was having a discussion today with some fellow electrical workers, we were talking about plug in commercial appliances.
They claim after the repair that a electrical safety certificate is required after the repair and the machine ( including 3 phase) is plugged back into the commercial building. I said I dont see the plug in machine as " part of an installation" so only requires a test and tag cert to prove it as electrical safe.
Your thoughts ?

You are correct, plug-in equipment is not part of an electrical installation as defined in the Electricity Act. Nor are permanently connected appliances.

For plug connected, the after-repair rules are in ESR 90.

For hard-wired; the act of reconnecting the equipment to the installation (if they have been disconnected) requires an ESC.
