Electrical wiring is like a piping system. The joints and ends need to be completely seal up (connected) or there are leaks.
A well designed eletrical systems will allow for the pemanent introduction of smoke. Once this system has been breached - POOF!! there's smoke. So the user must find the leak in the wiring and seal the offending cable and reapply the smoke. If all possible leaks are sealed - NO SMOKE.
We've all sen this smoke. Comes from stereo equipment, starters, batteries, even household appliances! Smoke systems come, primarily in 12v DC or 110v AC. But can be anywhere from AAA to megawatts!
So, to summarize - Contain The Smoke. And all your electricity will flow!
