Thanks for all your help guys.

The main water enters the house in lead for about 1m then is jointed to plastic for the remaining length.

also do I need to earth the main water pipe after the new tap?

Thanks, so would I be best taking a new cable to the bathroom from the CU and bond the bath pipes, sink and shower pipes? Sorry for so many questions... just a bit confused

Thanks for all your replys. There will be about 1m of lead water pipe left under the floor (the total run is about 5m) and the rest will be plastic. Would you need to supplementary bond an old cast iron bath?

Hi My dad has just bought a new house (1930s) and we are in the process of updating it all. It's previously had a dual rcd split load board fitted at some point. We are now having some plumbing done to replace lead pipes and fit central heating.. the plumber will replace half of the lead...

Hi, I am creating a project that will control some pumps via a microcontroler with relays etc. At the moment it is fed via some 1.5mm 3 core flex and a 13a plug, it then goes in to the common side of each relay and out to a fuse for each output. from there it then goes to some 0.75mm 3 core...

thanks for your reply. i'm just wanting to learn to be honest but i find it hard to work from the drawings for now as they confuse me a bit would the wiring be the same for any voltage? i.e 12v to 400v?

Hi could someone show me or tell me how to wire a start and stop button to a contractor so that it stays on when the on button is pressed and goes off when the stop button is pressed. Thanks

Yes it will be exposed for 95% of the run going in to junction boxes along the way for connection to the fittings

I have three new LED flood lights to put up on my house and wanted to know the correct type of cable to use as everyone seems to say the twin and earth used already is not suitable?

Great thanks

He has used black stuffing glands

we have had a new consumer unit fitted and it had to be moved 1m away due to size restrictions. The electrician has used an adaptable plastic box to place all the cables in to and then used crimps on each cable to extend it to the new consumer unit... is this correct?

if a three phase board is fully populated what would be the common thing to do to create more space? Would you mount another board at the side and bring its feed from a 3 pole breaker in the old board?

Thanks for your reply. I won't be doing the work it was just a question. The wires are all black and numbered 1,2,3 I presume that's for phase identification but I'd have to check. Am I correct in thinking that the fuse rating is to protect the cable and not the machine?

one of our friends has an industrial unit that he works out of for his joinery business and he has just got a new 3 phase planer. It has come wired in SY cable with a 16A 3 phase red plug on. Does he need to use the plug or can it be taken off and the cable be terminated directly in to a 3 phase...

Hi, Im working on a project for my very large aquarium that will do some basic monitoring for me. I need a common alarm sounder to sound and for it to light the corresponding indicator if any of the following happen: high temp, low temp, water leak i have a temp conroller for the hi/low temp...

The new one will not allow the cable to fit back in place as the old one did it only needs extending 7-8inches so thats why i thought to crimp it in the switch fuse
