How to use it
In a Philippine house the cable from the breaker runs in conduit to a junction box, where the wires are spliced: stripped, twisted together (pigtail) and wrapped in electrical tape, or joined with twist-on wire connectors. Every splice stays inside a box that you can reach, with its cover on (PEC).
