Hi, I've got a customer that has had 7 electric Velux windows put in an extension. Each one comes fitted with a 3 pin plug. Normally I would cut the plugs off and extend the cable with a maintenance free JB down to a FCU at socket level. The customer is adamant he doesn't want that many FCUs...

Hi, I'm going to be putting a supply in for a hot tub. Something I haven't done before. I planned on putting a 6mm twin and earth from the consumer unit to an external rotary isolator, connecting the cpc straight through to a SY flex which will run to the hot tub. However, the company fitting...

Hi guys, I've just rewired a property that has a TNS earthing arrangement. The main earth is attached to the incoming supply cable with a BS 951 Bonding clamp. I was under the impression that this was unacceptable so rang the distributor who said it was ok. I then rang NAPIT who confirmed it...

Hi, I have a couple of 600x600 fittings with 4x 2ft fluorescent tubes in them (the type you get in suspended ceilings). I see you can get 2ft LED tubes and just wondered if they are a direct replacement or do the ballasts need bypassing? Seems to be different answers on different sites. Thanks

Hi all, I've currently got a Megger MFT1720 multifunction tester. Had it just under 3 years and I'm not happy with it. It has recently failed a calibration and also the right hand dial seems to have a poor connection between high and low current loop impedance. Im sending it back to Megger...

Hi Guys, Just done a EICR on a domestic property. Its about 10-15years old so alls good wiring wise. The only observations are that its a 16th edition board so lighting circuits with cables buried in walls less then 50mm not rcd protected. Guessing this would be Code 3? However there is no...

Hi guys, I've been asked to install some down lights in a bathroom. The lighting circuit isn't RCD protected in the consumer unit and there are no spare ways to move it over. (Its the old type of wylex board that won't fit RCBO's in either) Is it ok to put a 2 Way RCD consumer unit in next to...

Hi guys A customer has asked what cable size he would need for an out building in his back garden. In the out building, he's planning on having 3 or 4 general use sockets, 2 lights inside and 6 pillar lights down the garden. The cable length needed to the consumer unit is 85m and will be SWA...

Hi guys. Is it ok to put 3 x single phase consumer units on a 3 phase supply. One per phase out of each cut out then a henley block connecting the neutrals? Would put a 3 phase board on but theres only single phase circuits and the amount of RCBO's needed would be £££'s. Thanks in advance!

Hi guys Ive just done a EICR at a doctors surgery. Theres a single phase rewireable fuse board for the main circuits (lights, rings etc) and a separate 3 phase board for the electric convector heater radials. This 3Ph board is supplied from another enclosure with a contactor in it (see pic)...

Hi guys Just been to a job where they had a 2.75-3kW under sink water heater on a plug and socket. The live in the plug had melted. I changed this arrangement for a switched fused spur treating it as if it was a standard immersion heater making sure all connections are tight as i thought this...

Hi. Ive just been to a customers house that has asked to have the gas and water bonding done as a previous electrician had said he couldn't sign it off as there was no bonding. I asked what he was signing off and the customer didnt really know. It turns out he had had a new bathroom fitted by...

Hi! Where do I find the different codes for departures from 7671? e.g Wiring that is the old colours (Red/Yellow/Blue) is code 4 - not dangerous etc. Also, I changed a consumer unit for a customer and the only things Ive picked up on the test is that its the old colours as mentioned above, no...

Hi! Don't know if anyone can help? Im currently doing a part P upgrade on a customers house. He had an old rewirable fuse board that had a 63A switch fuse off it that feeds his tennis court lights. Its wired from the switch fuse to an outside JB in 16mm 3core SWA then 2.5 SWA after that to the...
