Discuss RCD Test on lighting circuit protected by RCBOs in the UK Electrical Forum area at ElectriciansForums.net
The cap pins fell off of my BC one, not happy considering the cost of the things!
i'm with spin on this. RCD might perform perfectly when loads are dissed, but a neutral fault somewhere on the installation could prevent it from operating. the whole purpose of a RCD is to protect against accidental touching of a live part anywhere on the installation. therefore it should be tested as a real life situation, not dissed from the circuits. that's like something working in the lab. but failing in service. tin hat, where art thou?
Just noting that for all the effort of getting the screw-ins it still means you have to access near live terminals. That said, it's a nightmare holding three leads in the air while pressing a button so those screw-ins are worth their weight.
Explain how?RCD might perform perfectly when loads are dissed, but a neutral fault somewhere on the installation could prevent it from operating
Agree with Tel, long story which I previously recounted (RB explained, I think) earth neutral fault, stopped RCD functioning.Explain how?
Can't see how. Also struggling to see the point in testing multiple circuits at the end of each when fed from a common RCD? I was always taught to test an RCD at the board, and have always done so.Agree with Tel, long story which I previously recounted (RB explained, I think) earth neutral fault, stopped RCD functioning.
