Step on electric underfloor heating help!

[Amaryllis92]

Hello! Today we had electric underfloor heating glued to the floor. My partner, who weighs 115 kg, walked in with shoes and stepped on the underfloor heating! Have the cables broken now? It's an ebeco cable kit 200.

Very unlikely that they wouldn't withstand it. But there are shoes and then there are shoes... The cable can withstand about as much as a lamp cord, at the very least. So if lamp cords don't usually spark when he steps on them, nothing should have happened here either.

It can be a bit sensitive if the cable is mounted on top of a network of rebar (common), as it can create very high point pressure when stepped on. A bit like placing a dull knife under a cable and standing on it.

They were regular sneakers and the cable is glued to the concrete. but he weighs 115kg and walked around there on the cables... :/

You may measure, a measurement schedule is included that indicates how to measure that the cables are ok.

can't only an electrician do that? the electrician measured before my partner walked around :/

Even if the cable is 4mm? :/

However, it can be a bit tricky for us private individuals. IF you are going to check the cable, you need to measure with an insulation tester (an instrument that applies 250 - 1000V on the cable). That's not something commonly found in the toolkit of non-electricians.

The installer has hopefully performed a measurement after the cable was laid out. The next measurement should be done after embedding.

but it feels a bit worrying if we embed it and it doesn't work :/ can you walk on the loops with shoes?

but it feels like if we pour and it doesn't work :/ can you step on the loops with shoes?

The only answer you can get is to have the electrician measure again

It's silly to pour now when you're uncertain. It's much easier to fix now than afterwards.

The answer should be: probably nothing is broken. If you want to be completely sure, pay an electrician to measure again before you cast.

 

[hempularen]

As I said, I believe the cable will make it, but it is certainly less suitable. In practice, the craftsmen who are casting will step on the cable with shoes on their feet. They may need to slog through the casting, so you can't see any cable.

As I said, I think the cable will be fine, but it is clearly less suitable. In practice, the workers pouring the concrete will step on the cable with shoes on their feet. They might need to step into the pour, so you won't see any cable.

ashamed to call the electrician, let's hope they manage

IF you measure and those who then cast break it, their insurance is what applies. If you don't measure and it doesn't work afterwards, it will be difficult to prove who made the mistake.

Your shame in calling the electrician is therefore greater than what you feel about a potentially non-functioning underfloor heating? Okay, in that case go ahead.

If I were you, I would call. For peace of mind's sake.

Personally, I think there's no danger.

 

[Amaryllis92]

but do craftsmen usually step on these? feels like it should hold up to being walked on?
