Is there a chance Dual RCD Consumers could be "banned " from rentals soon?

[LukeD]

Client has purchased a night flat in Edinburgh. Its perfect for using as a ST rental during the festival as the agents claim £6k a week is the value based on rooms and location. It was nicely decorated in 2018 and has a twin RCD Board . Wiring etc etc looks very good .Its a tidy install , sockets etc all good . Worth leaving as it is or will he hit a "wall" in the next few years with new regs about not having RCBO board do you thinK ? IT has a FRESH EICR that showed no issues .But recommended a board swap . He has plans to remodel it in 5-7 years and will be doing a full rewire etc etc then .

You mean switching the line ?

That's all that's needed

If there is little risk of a "hot" neutral then that is true. You get the full isolation for testing and selectivity with any up-stream RCD protection for N-E faults.

However, if you do get a hot N situation then you rely on the RCD action for tripping, and that is far slower than the usual magnetic part of the MCB side of things. Also most SP+N type devices only have the arc-chute in the L side so a high energy N current fault might total the device, etc.

Ohh "Arc-Chute" and new phrase to throw about to customers. Thanks for that.

Looking forward to it all been "wireless' . Just stick a socket up etc and it auto links. Headaches could be bad though !

If the agents are correct at 6k a night during festival season..... you could get a gold plated CU with all bells and whistles....

£6k a week , not a night !

Still though.

6k could buy you a lot of dp rcbo’s

That's what I was wondering. Essentially our single module 1P+N RCBO does exactly the same as a 2 module device?

In the UK it generally will do yes. But in another country where supply polarity cannot be guaranteed or where neither pole of the supply may he reliably connected to earth then the difference should be obvious.

I'm not intimately familiar with conventions of electricity supplies in other countries. It's easy to forget that polarity is of less importance in other parts of the world and that reliable earth connections often aren't considered to be of as much importance as perhaps they ought to be.
