Checked the CU in the flat where I want to add the panel heaters it has 2 of 5A lighting fuseholders, 1 of 15A (I presume for immersion) and 3 of 30A into 2 of the 30A is a single core live which both look thicker than 2.5mm and the 3rd 30A seems to have 2 live cores but each core sort of looks...

Thanks, But 2 nd consumer unit is for house extension on other side of fat wall - not practical to run all cables from existing CU. Extension will have bedroom, shower room and utility room. Which presumably will require more than 32 amp mcb and thicker cable.

Please can some one tell me what the standard procedure / order is with getting a second consumer unit fitted in an extension - so I don't end up getting the elec out twice or more? Thanks

We would like to install a wood burner with boiler that will provide hot water to a thermal store preferably by gravity and have enough heat output for the room it is located in. We would also like to connect into the thermal store an oil boiler for times when we don't have the burner running...

Another question if I am not asking too many. We have an Incoming mains (PME system), which splits to 1.storage heater system with meter and CU. 2.The other part of the split goes to normal meter connected to CU in main part of house then from a 30A rewireable fuse in this CU runs a cable...

I DO just want to remove the panel heaters not the CU. I wanted to know in question 1 basically if the CU is off is it safe for me to unwire the panel heaters (2) from the CU. Might mention that i am a Her and not a He - not that it is of great significance I guess - well in this situation...

Hi I have 2 questions 1.I would like to remove from our new house a couple of Dimplex panel heaters 1250W which are wired into one of the CUs of the storage heater system (main incoming cable divides and goes to 2 meters 1 for normal elec and CU and 1 to storage heater / immersion / panel...

Big thanks for your help here - I feel more comfortable again having digested all this. Just finished a 4 gang - 2 way switch and I'm seeing cables now when I shut my eyes! Thanks again for all help.

Sorry to bring this to the top of the list but wanted to say thanks. Wired fan in and it works - sounds tired so guess need to replace at some point but thats a job for later.

If you can bear with me so I can work out how this works! Ok have measured 1 of the lighting circuits with own 5A fuse in 1.0mm Total cable in circuit is 56m Goes like this CU to JB1 is 2.1m then JB2 with switch cable 60cm and light cable 1m Feed from JB2 to JB3 is 4.7m at JB3 feed splits...

Er... can you believe it! my husband who i just spoke to has just admitted that HE infact unwired the fan when we moved in because it was distrurbing his loo experience!! :twisted: Have spoken to BG who don't sell fans anymore and as you can expect won't give any technical advice. There are...

Am in process of searching for manufacturer. it says BG on it embossed on the plastic and there seems to be no model no. May update the fan anyway. Just wasn't top of the list just now. Thanks

Previous owners unwired extraction fan in bathroom at the fan. have checked where this comes from and it is looped into bathroom light. The cable that goes from light to fan meets fan with red - live term, black to neutral terminal, there is a blank/empty switched live terminal,the earth wire...

does 4 - 6 m drops count as insanely long?

I presume the cable length calcs for lighting = all cable from CU to last JB INCLUDING light cable lengths and switch cable lengths coming off JBs - ??

The reason I was asking about the earths is because in one of the existing JB's all the earths were not connecting in with the feed cable earth and I thought this odd - I guess they did this due to lack of space. If I add on extra boxes then there should be ample space and I can rectify this...

Thanks, I think I will run the feed to a new box and put the new light into that so there are less cores in each terminal and plenty room for the earths. Not that this is relevant if i do it this way but out of interest from my original question do all light cable and switch cable earths...

Are these large JB's not good - I wasn't planning to rewire the whole house just add a few lights into the existing circuit which has 3 of these boxes each going to a seperate fuseholder in the CU. i thought they seemed quite good as all in one place. If I change to individual JB's would...

Am planning wiring an extra light into a circuit served by one big JB containing a strip of connectors which all lights and switches come from. There are 5 lights on the circuit and I am planning connecting in a 6 th : total 600W. Problem is I cannot get another earth wire into the connector...

i have a 3 gang switch. 1st gang is 1 way 2nd gang is 2 way 3rd gang is 1 way When I opened it up I expected to find 1 of 3 core switch cable and 2 of 2 core switch cable each gang has 4 terminals two labelled 1 and two labelled 2 However what i found is 1 of 2 core cable and 1 of...
