What can be insulated from the outside of the wire?
Pvc4 line slot is fixed to the maximum from the jar on the wall, and finally put the wire cover and insulation way too much, this is the most simple and most practical, but need to punch holes in the wall without impact drill, impact drill, with the 4 points PVC or pvc4 line pipe hose can
It is better to apply a PVC wire to separate the wires, and the wire output switch must be protected by electrical leakage (with a shorter type of action). Gas tank, gas tube to long inspection, determined not to leak occurred. This way you can use it safely.
I suggest you buy a few sets of tubes to wax on it, wax tube is used exclusively with insulated wire, and it is a soft tube, it is very convenient for you wire bending, it is PVC fiber tube: (1) temperature: 125 C; (2) bending after heat treatment: coating don't split, not out; (3) bending under low temperature: coating no dehiscence, not out; (4) the breakdown voltage: the median 2500V.
