Stainless Splashback Earth Bonding

[Mark Elvin]

As part of the kitchen re-modeling we are popping in some stainless splashbacks, two of them have socket cutouts in.

My question is do they require earth bonding as they have sockets it them as there is the potential, albeit small, for the splashback to become live.

According to guidelines, supplementary bonding is no longer required in kitchens.

Are kitchen circuits via an RCD or RCBO ?

But surley it's a good idea?

I had hoped you'd pick up on the hint- circuits protected by RCD or by individual RCBO would be technically the better option.

RCBO's

If you look at the time I posted, we must have hit submit at the same time, hence me "not picking up the hint"

I would bond the splash back

If a fault connection develops between Live and an un-bonded splashback then the splash back becomes a large area of Live metal work. The fault connection may be damaged insulation, dampness or other means. As the splash back is not bonded there will be no effective route from the splashback to earth for a fault current to flow so the RCD will not see un-balance while the splash back is live.

Only when there is a path to earth from the splash back will there be un-balance in the circuit to possibly trip the RCD. If that path is a human body with one hand on the splash back and the other hand on an earthed appliance then one hopes the current through the body is less than fatal and enough to trip the RCD

Sorry lost PC connection, as my previous post guidelines require no supp bonding in kitchens, but it is a large area with the potential to come live. So if in doubt bond it.

Thanks, I'll be doing that, belt & braces.

A splashback with cutouts for electrical sockets - really?

Yup, alot of the stuff in the kitchen is bespoke, only way to get what we want.

You'll be surprised at how little it costs.

Shame glass isn't as cheap....

HI Mark,
Are you going to post a couple of pics when its finished?
Sounds like it will be nice.

I agree with bernardgreen, if the stainless will be forming part of the enclosure for electrical accessories it will be an exposed conductive part.
Exposed conductive parts must be bonded.
There is no need to supplementary bond extraneous conductive parts in a kitchen such as water pipes.
