For 3 way switching, If the permanent feed is at switch 1 can the switched live be at switch 3 ? :?

Excellent. Thanks for the replies :wink: Is that definately the part no. for the diverter valve. Cant seem to find it. Have you got a link ? Cheers

Ill see if I can find a link The plumber was on about using some sort of relay in the circuit but I didnt quite know where. I didnt dismiss this until I got home & had a think. Cheers.

Ive got a situation where I wired a 12KW boiler into a new build & now an oil boiler has got to be installed. The programmer which is a Horstmann H37XL is controlling the heating at the moment. The customer wants the oil boiler to take over from the 12KW boiler but still have it as a backup...

it was a discussion goldberg. I was asking about rcbos not how to do my job. Anyway engineers for this particular maintenance company decide what cable and circuit breakers to use and i do the connections and testing.

Yes I did & the results were all >299. Only did it on 500V, maybe I should have done it on 1KV

Doing some electrical connections on the motorway for some CCTV & one of the connections to the camera is approx 500 metres from the supply. When I put the switch up on the RCBO it wouldnt reset. Disconnected all the load on the cable & it still wouldnt reset. Ive walked the length of the...

They were CFL type, 11w

yes yes yes yes I didnt expect to get 113V. If this is normal then fair enough.

I fitted some low energy shower downlights last week & customer complaing the light is not bright enough & its like a tunnel of light that comes out of the fitting. They are not the JCC ones though.

supply L & N voltages 246V with main sw off Ill be looking tomorrow because I couldnt get access but there was someone on site that said the supply had its own meter & cutout & was fed through a 100A type C Circuit breaker. The run from the meter to the office is about 10Metres in 25mm SWA &...

Testing a split load CU today that another Electrician had fitted. It was in a very small office. There is one ring with 6 sockets & 2 lighting circuits (1 for the kitchen & toilet & 1 for the main room) All CU switches were off & the circuits were connected in the CU, but when I measured...

We know that socket outlets need 30ma protection but what slightly concerns me is the NIC tech helpline says one thing, (but they are thinking in the real world) & other electricians say another. At the end of the day I'm getting paid anyway but I could have been doing something else. It...

I agree Pensdown but I could have argued the toss all day with the bloke & he started to do my head in. I cant believe the NIC will be taking another £450 or so, out my bank this month to stay registered with them. I cant re-type the whole conversation with the bloke but it was like talking to a...

BAS - Ive never met the Electrician that did the PIR's. The landlord gave me a list of things that electrician had found & it wasnt a PIR list. I've not done any certs as the landlord said the other electrician will check I have done whats on the list. Spoke to the NIC today (when I could...

OK no probs, just wanted an opinion. Plenty of room for everyone :wink:

Well its just not chipping it out is it. When you got x2 10mm cables coming in & out of the backbox from each side in plaster it isnt easy to make nice job of it.

Have you got a link to it, I cant find it. :wink:

No I cant BAS, tried it. It wouldnt be easy to split the tails either cause the meter box is about 3 metres away from the cu on the outside wall but I suppose I could put them on the surface in trunking.

Just started doing some maintenance for a landlord & the previous electrician had done PIR's in all the properties. Been running through the list of jobs & one of them is "no rcd on cooker circuit" (it has a socket) Now I could replace the double cooker switch with one without a socket but it...
