Re: How do I protect supply wires

The reason for the 30ft distance is I put the pig in the control box.
I don't want to be closer to the coil when it is running.
If I just put them in pvc and they get hit I'm afraid it might feed back to
me.
Do you think that a safety gap at the pig is sufficient?
