Electric underfloor heating

Adrians9 · Jun 23, 2023

Hi guys wonder if you can help.
Just laid some electric underfloor(not going to connect it myself) it’s the loose lay stuff thin stuff. I spaced it 50mm apart as per manufacture instructions, but once it was self levelled it pulled a few wires in to more like 40mm in a few places. Is this a hazard/fire risk?
Thanks very much in advance

Can't see any problem with that. As long as the cable hasn't been damaged. If you have a multimeter you can do a continuity test L - N. but for insulation testing you'd need a more specialised instrument, commonly called a Megger Tester.

Thanks for the reply telectrix. I’ve tested the resistance and it’s reading what it’s supposed to so the cables ok. My biggest concern was that if the cable does get bellow the 50mm minimum in the few places that the instructions say it could over heat and portentously cause a fire/ burn out. Am I otherthinking it?

Thanks
