Inline splice insulation. You can protect a low-voltage inline splice in a similar manner by wrapping the installed connector with four half-lapped layers of rubber mastic tape or rubber splicing tape, and then over-wrapping it with two half-lapped layers of premium vinyl electrical tape.

3M rubber tapes have operating temperatures ranging from 176°F (80°C) to 221°F (105°C). Some, like Scotch® Linerless Rubber Splicing Tape 130C and Rubber Splicing Tape 23, have overloads temperatures up to 266°F (130°C). Because of this high heat attribute; there are many industrial settings where it is common to use rubber tape in lower voltage applications to moisture seal, pad and insulate:
 

Thus, the well pump control box sits at the nexus of the entire system and powers its most important functions. Most people who need a well pump control box will buy one that’s designed to work with the specific type of pump they’re using, since the components are designed to work together at the correct voltage levels and are easier to service.
