Distribution Box Tap Changer

No-load tap changer (NLTC), also known as Off-circuit tap changer (OCTC) or De-energized tap changer (DETC), is a tap changer utilized in situations in which a transformer's turn ratio does not require frequent changing and it is permissible to de-energize the transformer system. This type of transformer is frequently employed in low power- low voltage transformers in which the tap point often may take the form of a transformer connection terminal, requiring the input line to be disconnected by.

The distribution box is energized

If a hot or neutral inside the motor touches the casing, the casing will be energized, resulting in a “fault current” through the ground wire. The ground wire (green) safely moves that fault current into the breaker panel, tripping the circuit. Don't connect anything to the ground.

Side tester ($10-20 at a hardware store), it's not full proof so it shouldn't be fully relied upon, but is usually enough to tell you if it's energized or not. Multi-meter/volt meter ($20-100's), requires you to touch the leads to the actual bare wires, risk of shock if you don't know what you're. A distribution box that fails without warning stops production and costs real money. When it shows trouble, act fast. Here are seven warning signs every facility engineer and maintenance manager should know.
