[graham123]

Anyone come across one of these? Are these a c3 on eicr?

 

[telectrix]

Obsolete voelcb. Bin it. I'd say a C2.

 

[dingledong]

Does it work ok

Obsolete voelcb. Bin it. I'd say a C2.

or keep it as an isolator

 

[dingledong]

If it works and tests out ok then it's a code 3

Where do you get a tester from for them?

 

[graham123]

bs 4293 is not a volelcb

 

[telectrix]

i stand corrected. looks like it may be a 500mA RCD.

 

[Sintra]

Looks like it's 300mA.

 

[telectrix]

can't make out from the pic if it says 0.3A or 0.5A.

 

[Plonker 3]

So what does the ELCB stand for printed on the label?

 

[graham123]

earth leakage circuit breaker

 

[Plonker 3]

can't make out from the pic if it says 0.3A or 0.5A.

Definitely 0.5

 

[telectrix]

you must have been to specsavers. i thought it was 0.5, but not clear enough to be sure.

 

[Plonker 3]

Here's a blown up picture of the label for you tel

 

[telectrix]

cheers.

 

[dingledong]

I had roughly the same thing spoke to Nicky help line said I could leave it in place not the same as the pick but something similar

IET Forums - Old RCD (Crabtree)

 

[Sparky Pat]

As defined by 14th edition of wiring regs it is a current operated earth leakage circuit breaker [now known as an rcd] as opposed to a voltage operated earth leakage circuit breaker which are no longer permitted since the 15th edition. It is rated at 500ma.

 

[ETAS]

A voltage operated earth leakage circuit breaker is generally coloured black and are slimmer than an current operated earth leakage circuit breaker.

A voelcb will also have 2 x earth wires connected to it (normally the earth terminals are on the bottom face in the middle), 1 x from the consumer unit and 1 x going to the earth rod, whereas an current operated elcb will not have any earths connected to it.
