GFEP Benefit

[Trlsend]

Code compliance aside, what practical benefit is gained by protecting a snow melt cable encased in concrete? If GFEPs protect "equipment" not "people" I don't see what protection is provided to a resistive cable. If the concrete imbedded cable somehow breaks down and leaks - isn't the cable toast? Thanks

Not necessarily. Depends on the resistance of the concrete. And if the OCPD did not trip you might have hazardous voltage gradients in the concrete with touch or step potential.
