Apology accepted. I was not offended by this, rather puzzled by your aggressive tone and inuendo, and totally baffled by talk of local isolators in pubs, do you have me confused with someone else ?? From the wiki "An opinion is a person's ideas and thoughts towards something. It is an...

It doesn't need to be an RCD socket. However, you will need to test amongst other things, the existing RCD which protects the DS ring, along with the EFL impedance, insulation resistance, R1+R2, R1, Rn and R2 end to end resistances of the existing ring.

How do you work on lighting circuits ? How do you work on socket outlet circuits ?

Again, this is confusing emergency switching and isolation. If there is an earth fault on the shower then the RCD will trip. If the circuit is overloaded then the MCB will trip. I've never said that a pull switch is not desirable or that I would not fit one, just debating that the ommision...

Fair point, and I agree, if the MI state a separate DP switch is required then one must be installed. However this is a slightly different debate, my post was about compliance with BS7671 and requirements for isolation. And its nothing to do with saving a tenner or whatever, its about what...

I didn't comment because I don't know what screwfix sparks are, and furthermore whether they believe "local isolators" are only required in pubs !! :?

Who is this "screwfix spark" that you speak of ? Why does having a pull cord offer peace of mind ? What are the "consequences" of not having one ?

Absolutely. Its for ISOLATION of the shower circuit not emergency switching. The main switch could be the means of isolation for all circuits, except that it contravenes the requirement for the ability to isolate individual accessories or circuits. The only reason a DP switch is required for...

On what basis are your opinions more worthy than mine or any others on this forum ? What have I said that is **** ? 131.14.01 - "Effective means suitabley placed for ready operation shall be placed so that all voltage may be cut off from every installation from every circuit thereof and...

412-03-01 & 412-03-02 :oops:

Please state the reg that details this. My understanding was that it was all sides of a CU, having said that In fact i'm not sure which if any reg says its IP44 an any side?!

Adequate spacing and fixings to secure it the the wall/ceiling ! Yes silicone.

The tails coming in from the bottom of the CU seem to have space big enough for a bit of 1mm wire ....

Blimey RF, I spose you ended up replacing the CU, since the cover didn't fit, and was loose because the screws were snapped, the perspex cover was half open, you had loose contacts on the main switch, the earth bar was hanging out, you had the wrong OCP devices fitted, the wiring was a mess...

Even if they are not installed in a compliant manner, e.g to IP4X :wink: Even better to turn off the main switch before removing the cover :wink: :wink:

If the cables have to be surface mounted on the ceiling/walls use trunking. Don't use self adhesive as the steam/heat in there will cause it to fall off. Don't put any junction boxes in the bathroom, simply drill thru into adjacent cupboard, run in the cable, seal around the hole, and butt...

Lets be realistic. My mate can't afford his mortgage on a big house. He can't afford to sell it becasue the price has plumeted His best bet is to let it to students for a few years to weather the storm. The uni/labc inist that as its multiple occupancy he has to have linked mains smoke alarms...

Resurrecting this old post as had a debate on the same subject today. In my opinion, a situation where a separate shower CU is installed with say a 63A/30ma RCD as the main switch or indeed an RCBO then this can satisfy the requirements for isolation as well as OPD/fault protection without the...

Ah thats the job for me, 3 hours on an hourly rate, tea drinkng watching a luminaire to make sure it stays on :lol: More of those please !! Seriously though, cant see that the breaker can't take 12 operations a year without mechanical fatigue foe a good few years..

Fair point. How often should the test be performed then ?
