Hi all,

On Friday I will be fitting a new bath which for reasons unrelated to
this thread (well, not entirely I suppose) will be made of steel.

Our bathroom currently has no equipotential bonding, and I am aware that
in order to comply with the regs I will either need to install
equipotential bonding or upgrade my installation to meet the 17th
edition regs.

Now, I'm aware that there is probably more to the 17th Edition than
simply sticking some RCBOs in my CU, but I was wondering if that would
be enough to nagate the need for me to install equipotential bonding.

At the moment, my CU is a split load that consists of the following
(please bear in mind it's a small terraced house):

RCD Side
Whole house sockets (ring)
Kitchen Sockets (ring)
Oven (radial)
Immersion Heater (radial)

Non-RCD side
Upstairs lighting (including bathroom fan)
Downstairs lighting

Now, I understand the dangers of putting either of the lighting circuits
on the RCD side, but what if I replced them with RCBOs? Would this be
enough to not require equipotential bonding as there would be no
circuits in the house without RCD protection.

Any thoughts/opinions welcomed.

Thanks,
Richard.
