RCCB fitting ( newbie post)

[StaffBull]

Could anybody let me know how to install a RCCB correctly

2 Pole

my working of it is L & N come out of an MCB (40A)
and in to the RCCB, L & N come out of the other side of the RCCB and out to
the shower ( earth goes direct to shower from ground block on consumenr unit
as there is no earth connection on RCCB)

any help much appreciated.

I have been an electrician for 35 plus years, I have never heard of this
term RCCB.
You aint from the US are you.... ?

Why assume that he is from the US? There is life outside the US you know!

RCCB = Residual Current Circuit Breaker

That's about the measure of it, but in the majority of cases the neutral
"comes out" of a neutral block in the consumer unit, not the MCB.

Although you can get SPSN (Single Pole Switched Neutral) consumer units. In
this instance the neutral would be connected in the MCB, these SPSN consumer
units are rare in the UK and are mainly installed in local authority
dwellings.

Some manufacturers use electronics in the RCCB, these types can have a small
flying lead usually coloured white that should be connected to earth.

You could always use a RCBO which is a combined MCB/RCCB in one unit.

If in doubt get an NICEIC approved contractor to do the work.

Hope that helps

Thanks, the neutral does indeed come out of a neutral block on the consumer
unit.

I said he was not from the US. I was trying to learn something. Thanks

I would suggest getting a 80 amp 30ma rcd and fit it to the supply side of
your fuseboard then all the circuits would be protected by the rcd (only try
this if you can isolate the supply first via a double pole switch )

Protecting your whole installation with a single 30mA RCD is
contrary to the Wiring Regs (but sadly all too common).

US = GFCI
UK = RCD (Residual current device)
