RCD Testing - Remove devices prior to testing

[dazj90]

I've got a 3 phase DB with individual RCBO's supplying various equipment, Fire Alarm Controller/Water Heaters/Office Sockets/Office Lighting/Air Conditioning Controller.

GN3 suggests "Any load or appliances should be disconnected prior to testing", would it be ok remove the supply at the RCBO for this and is it necessary to remove the load?

Just take line and neutral out of the RCBO (work safely) or make sure the kit is switched off before testing.

Would removing the fuse from a spur be sufficient enough to remove the load as there are a couple of circuits that feed a spur then the device.
Full arc flash gear will be worn under companies rules.

Also , is there a standard form to complete with just RCD quarterly test results, or would I just complete the RCD times section on the EICR form?

 

[Richard Burns]

Yes removing the fuse would be sufficient, or just switching the spur off if it has a switch.

I do not believe there is a standard form for quarterly RCD testing.
I would either create your own form or modify say a minor works certificate to an RCD testing report.
Something like this depending on what you need to report
