Was that a dumb question? I want a socket either side of the cooker, surely the cables must have to cross over. Steve. ____________________________________ lynda, moderator please note forum rules, general information, item g

Is it acceptable during an electrical installation for one cable to cross over the top of another at right angles? Specifically I will have the oven cable coming down from ceiling level and I want the two ring cables to cross over the oven cable at right angles 150mm above the worktop. Steve.

Had a good read and then did some measurements to work out PSC Used the shower as a 35A load and measured the supply voltage drop. Unloaded voltage 235v - loaded voltage 231v (both measured at CU) R=V/I R=4/35 R=114 mohms PSC = 240/0.114 PSC = 2100 A (this ties in...

Adam, thanks for the explanation. I just found a whole section in my library book that explains that (Electricians guide to BS7671 I think). I'll have a good read of that tonight. Steve.

I'm in Manchester. I phoned my electric supplier (the ones I pay for my electric), EDF energy. They then had to phone someone else to see if I could have it done for free or not. They then got back to me after ten minutes and said that I could have it done for free. I've an appointment on the...

Just keen to learn about the theory really. Don't think much thought went into putting the shower in (that was done by previous owners). So just wanted to make sure it would be safe. My job is electronics so I do understand a lot of what your saying about your adiabatic calculation. I guess you...

Just curious, what's a DI?

Adam, so what is the requirement for the MCB selection? Can you use a 40A breaker to protect a cable rated at 38A ? and why is that possible? Thanks in advance. Steve. PS planning on getting rid of the electric shower soon to fit a combi powered mixer. Just want to the electric one to be safe...

Thanks Fred for the tips. I'm doing a similar job to you and am a bit apprehensive about the BCO as I guess you were too. I plan to use dot and dab with plasterboard too as the plastering on my main kitchen wall is attrocious and can't afford a plasterer. I was going to clip the cables directly...

Planning the fitting of a new split load consumer unit. It's a 100A main 80A RCD type. On the 80A RCD side I plan to fit; Shower 7.8 kW - 34A Kitchen sockets 32A ring Downstairs sockets 32A ring Upstairs sockets 32A ring Is this acceptable practice or not? I've been reading about...

Are there any guidelines for the proximity of a cooker switch to a gas hob? I know it shouldn't be behind the hob and that sockets should be 300mm form the hob edge. Not sure about the cooker switch though. I'd like to put it about 200mm from one edge but can easily put it at 300mm if that's...

Glad it went well with the BCO. Just a few questions really as I'll be meeting up with the BCO in April. Is he coming back or is that it? Did you attach the sockets etc. to the wiring or have you still got to do that? What conduit did you use? How did you fix that conduit to the wall? and...

I guess I could remove the trunking and clip the cable direct to the wall and then I should be able to use a 40A MCB. Thoughts on that please.

Sorry, I should have said that the cable is T+E, not single core. Steve.

I have a shower (7.8kW @ 230V, 34A) connected on to 15 metres of 6mm squared cable protected by a 45 amp MCB. The shower cable runs from the CU then up the wall on its own in a approx 2 metre length of white plastic trunking. The cable then goes under floorboards and then up the shower wall in a...

Thanks for all the replies. I'm going to use 25mm for everything except the cooker switch and ccu which will be 35mm. Steve.

Decided not to bother with conduit or boxed in cables. I will use the safe zones at the edge and top of the wall for running the oven cable. The ring will run in the safe zone defined by the socket boxes. I'll then plasterboard (direct bond to the brick) over to give a good surface for tiling...

Hope someone can help with recommended backbox sizes for the following: Unswitched single socket Unswitched 20 A flex outlet Switched FCU 45A cooker switch (without socket) 45A CCU Switched double socket I had a quick look but didn't see this info anywhere. Cheers, Steve.

Sounds like the 'Hamer house of Horrors' to me. :lol:

Is it acceptable to run cables under the floor joists and just let them rest on the subfloor? The reason I ask is that I am running some cables down the hallway to the kitchen. I pulled up some floorboards at each end and I can pull the cables through but if I have to clip them under each joist...
