if you have an earth leakage circuit breaker do you also need a separate earth cable?

 

[binky]

RCDs don't need an earth. Why do you ask?

Gas engineer was grumbling about no earth showing up on his test meter.

 

[ProDave]

You still need to provide an earth to all switches and sockets AND the gas pipe.

An RCD is for additional protection., not to replace an earth conductor.

Some (class 2) appliances do not need an earth, they will be supplied with a 2 core cable, but other class 1 appliances do need an earth, and could be positively dangerous if no earth was connected.

My advice would be get a spark to come and do some very basic tests on your incoming supply / fuseboard

an RCD does not need an earth connected to it to function (some RCBO's do though), however regulations require an earth in each circuit and to gas & water etc

Thank you. Spark coming soon anyway.

Please let us know what he finds / says and writes on his invoice?

And please include his address and bank account details, so we can do some further background checks!

:innocent

Thats just dumb ...............

:innocent No to that. He is very busy and won't be for a few weeks.

"No to that. He is very busy and won't be for a few weeks."

So the BG man questions the earthing in your property and you are happy to wait a few weeks before its checked out.

Really?

Don't have much choice he is the only sparky I trust. Moved to this house 2 years ago has probably been like that for years.

 

[Andy™]

itll be fine, it can only kill you once. without warning

Chances are BG bloke doesn't know what he's on about rather than there being a proper fault. The number of times BG have failed installations because their test gear doesn't cope with earth rods.....I lost count years ago.

Yes... they also like to make work for themselves, they get paid incentives I believe.

Just out of interest @Andrew Scott how old is this device (elcb RCD rcbo rccd)???

This is a category of devices, which are used to protect instruments, circuits and operators, while Earth leakage. Early ELCBs are voltage sensing devices, which are now replaced by current sensing devices (RCD/RCCB). Usually voltage sensing devices are called ELCB and current sensing devices are called RCCB.


Voltage sensing ELCBs were first introduced about sixty years ago. Current sensing ELCBs were first introduced about forty years ago. For many years, the voltage operated ELCB and the differential current operated ELCB were both referred to as ELCBs because it was a simpler name to remember. But the use of a common name for two different devices gave rise to considerable confusion in the electrical industry.[citation needed]

Only know more than 2years.

 

[Andy™]

since you only know 'more than 2 years', does that mean you moved in 2 years ago? if so, did you have the wiring tested then? if you did, any problems would have been noted then, although its still possible that something has failed since then

Didn't have it tested as it all looked quite new.

Will phone electrician tomorrow.

 

[Andy™]

his mate from the pub could have changed the board, fitted a few sockets etc, bodged the who thing but never mind, it looks new so it must be fine

dont take this the wrong way, but yet again another person who has no interest in checking the safety of their wiring, and only does something once told something is not right, someones had a shock or something doesnt work. its not as if it can kill at any moment without any warning...
