Good point. Maybe I should remove the tape.

Thanks!!

Perhaps the shielding should be tied into the silver ground installed in the zombie-apocalypse safe room.

Would this solve the overheating too?

Thanks!!

The romex is now quazi MC cable, the metallic quality will act as a heat sink and help dissipate heat from the NM cable, so no problem there. And for sure there's no electric heater on the circuit, that's otherwise known as an EMF"death ray" machine!

Please note there is no insulation in this interior wall.

This is the tape: https://www.uline.com/Product/Detail...B&gclsrc=aw.ds

Seems there is some disagreement in this forum as to whether this is safe or not.

I sure would like to se some empirical data on the efficacy of such an installation.

A million huh? Care to link to a few?

It's good that you came here expecting jokes, because the whole thing IS a joke. I bet you are "gluten intolerant" as well?

Re: Is aluminum tape around power cables for EMF reduction unsafe?


Clearly installed by someone who doesn't have much knowledge about emf, rf or wave propagation.......

If you were really worried I would have lined the walls with the tape instead of the wires. It would have been more effective. Especially he outer walls, turning your house into a faraday cage. And no, your cell phones wouldn't work anymore.

Although I offer this suggestion, I think it's far fetched..... I live at the end of a runway of a major international airport. I don't worry about stray emf...

Cheers!

I would think any electrical inspector seeing such a set up would not like it at all ! Because you have modified the way the electrical cables are used. This could then Lead to insurance issues. It is simply risky because it is untested and possibly against code as your using cables in ways not approved by the cable makers.
