    Actually DC is used to stop fibrillation, and that process is called defib. :)
    DC can also be used to restart normal rhythm from a flat line state.

    You cannot distinguish power in from power out by looking at the voltage with an NCV. But it only one wire shows hot you can be pretty confident it is going in, not coming out.

    And what you learn about cementing two pieces of PVC together is wrong.

    With a power meter, you would still have to measure current at some point to figure out which heater was bad.
    But at least you would know to take that mold out of service immediately.

    Probably not the best solution when the box and remote are in different rooms. It would get the signal past the cabinet doors though.
