    Opinion On Cable Ampacity in Thermal Insulation

    UK Thermal breaker to derate circuit?

    Hi chaps and chapettes, I have a buried 6mm SWA 32a radial circuit powering a single 32a commando/ceeform, i'm looking to add a 16a ceeform for convenience. Can I use a thermal-magnetic breaker to derate to 16a. There isn't space for a 2 way CU so would this be my best option? Thanks.

    Hi guys. Any of you have thermal cameras? If so what are your thoughts? which ones do you have? Has anyone got the new FLIR one for smartphones?

    Thermal Cameras

    I see the prices have come down over the last few years and also there are options that link to your phone or ipad. Are these any good? What are your recommendations for a thermal camera for basic electrical maintenance work for someone who's on a limited budget??

    Thermal insulation covering cable

    I'm doing a garage conversion. 70mm insulation on block then an inch gap battened on top, then 35mm insulating board. Where's best for the cable to go in terms of derating etc... Cheers.

    Motor protection

    Peeps, I have been asked to run a supply for a single phase, 3.2a extract fan (systemair AW500E4). Is it a requirement, recommended or just good practice to include thermal overload protection in such a situation? Thanks.

    Thermal Store problems

    Hi guys (and gals) I hope you can help me. Will try to keep it fairly brief! :grin: Have a Torrent ECO with woodburner downstairs, so gravity. All working well for the past year, apart from rads getting hot then cool (as the water gets pushed round the system) so instead of standing with my...

    Thermal imaging camera, any recommendations on the budget end?

    Not something I really need so don't want to spend a lot, but toying with the idea of getting a cheap one to see if it comes in useful, say locating underfloor heating elements or bad connections, and perhaps a look at the house from outside see where the insulation may be lacking (have my...

    What do you think of these thermal indicators?
