If,after the stopcock the installation pipework is of copper then yes it must be bonded back to your MAIN EARTHING TERMINAL. All bonding clamps must be accessible for test/inspection.

What you can do is turn that current radial into a ring and then you can utilize that spare 32A you have in your C.U. BUT ...if i were you id call an electrician out to chat to him/her about what is needed to complete this work as RCD protection will need to be considered as well as...

Depending on how you lighting circuit is wired in the first place depends if you can run another light from the switch. Most lighting circuits are looped at the roses but some are looped at the switches,meaning you have a perm live and neutral. If your lighting is looped at the switch then yes...

JB`s under a floor?

O.k first thing first... What wattage is the lamp ? Second... Go buy yourself a multimeter and double check the length of cable for the section between FCU and luminair for continuity. Third... Try changing the FCU plate for a new one as sometimes cheap makes could be faulty and while your...

Whenever you add/extend a circuit then the whole circuit must be tested as the more cable you add then the higher the resistance thus meaning your R1+R2 for said circuit will have increased.

You can extend using choc blocks but due to space constraints in the rear of the backbox with the socket inserted, crimping would be more favourable.

Personally, if I was fitting Class 1 lighting outside I would make it 0.4 second disconnection time.

Yes you can do this as long as your new extension doesn't put too much on to the circuits Earth fault loop. If the ring is run in 2.5mm twin and earth then your spur should be in the same size cable to a suitable FCU,from there,depending on the power the new light is pulling you can run a...

Cant see much wrong if the FCU is labeled up as to its purpose and like you have done already marked up on the C.U as to the purpose for the 16amp MCB. Suppose you could draw out a diagram with measurements for the dedicated circuit and leave them inside the C.U cupboard. I know you...

Not too sure what the foam is made of but its a formula that damp cannot affect i suppose...good question and an answer im not sure on :? . As for cables going to and from a consumer unit again they `should not` be run in cavities, they should be run surface mounted to floor/ceiling voids or...

No you cant run a cable in between the cavity of the walls as any damp that DOES come through the exterior brickwork/mortar will use the cable to bridge to the interior wall.

As mentioned above a shaver outlet can be spurred off the lighting circuit and personally if it were me id do just that. As for the extractor remember the wiring will be slightly different if you have a run over type fan i.e 3 pole... perm live...neutral and switch. I always install i 3 pole...

Get in an electrician if your not to confident about carrying out inspection work on your dwellings electrics. BUT If you are confident then... Are there any other bulbs blowing on that particular circuit? If not it could be down to either loose connections in the terminals in said...

Ive proberbly seen about 5 up here in stockport Secure....most others use Meggers now but i was lucky as one day i was in my wholesalers on hillgate and the Alphatek rep was in...so i collard him in the car park to show me the ins and outs of my Installtest.

All cables `should` be kept a good distance from hot pipes as a cable actually touching a hot pipe can be melted.As long as the cable isn't running parallel with the pipe you could get away with placing some insulation between the short section where the pipe and cable meet (i.e no more than...

If you join two spurs from different sockets you will then have made a ring on a ring...Not good really. No earth in some appliances is due to said appliance being double insulated (classII) ,look for the symbol on double insulated equipment bearing a small box within a box.

What you can do is to run the cable from the existing socket,through the wall to a fused connection unit incorporating a 13 amp fuse and from that fused connection unit you can then put your two new sockets in as the 13 amp fuse will protect the cables and two new sockets. BUT As both...

Mechanical failure....buy a new one and replace it. edited.... BARRRR HUMBUG

When a consumer unit is replaced by a competent person,it is up to that competent person to carry out a series of tests to ensure the existing installation is up to and meets the exsisting regulations. Did you receive an Electrical Intallations certificate and inspection and tests sheets from...
