UK Old 8.5K shower wired to 30 amp fuse with no RCD. Is it still safe & ok to use?

[koko88]

8.5K shower unit is wired to plastic box consumer unit to 30 amp cartridge fuse with no RCD

It’s the original shower installed when the house was built around 1995

The shower is still fully working after all these years, never blowing the cartridge fuse before

Am I right to presume RCD wasn’t required during installation in 1995?

Is it still safe to use with no RCD or am I breaking electrical regulation law?

Do I need the shower circuit updated with RCD fitted to comply with electrical regulation law or just leave it?

All the kitchen sink, bathroom & toilet basin pipes have Earth bonding around the house so is this supplementary bonding?

Can a new 3 amp Mira XS manual Shower operate with a 30amp unit, from old electric shower.

A 30A supply could be altered to make it suitable by an electrician yes.

Agreed.
What I was wondering is whether changing types of shower and modifying the circuit to include appropriate overload protection still considered a like-for-like replacement?
Personally I'd prefer to be dragging things up to date and complying with the requirement that all circuits supplying a bathroom have RCD protection. I think that's in his best interests really.
I'd also be checking supplementary bonding is up to scratch if leaving it on a rewireable fuse board.

Thanku very much indeed for your wise and good info. I have been quoted £140 to fit a new RCD ( 5 Amp) unit, and disable the 30 amp old HRC electric shower unit.Unless anyone disagrees with this please advise.

It’s hard to advise without seeing what you’ve already got installed. Even then, nothing beats a site visit where a proper appreciation of the installation can take place.

I’d say you need an electrician to come round and take a look. £140 seems way too cheap in my eyes.
