NEC

[securespark]

Not the building opened in 1976, the wiring code in the US!

Despite being called NEC, it seems it is far from "N".

Different inspectors in different areas may demand certain methods are used over others, ie sometimes receptacles and switches can be "wired through" and other times you have to "pigtail".

Many sockets have two sets of terminals, so you connect one set to one and the other to the other set. But if this is disallowed, you have to join the two together with a third "pigtail", which is bent over and attached to one screw or sometimes the accessory has a terminal similar to ours.

Seems crazy to make life difficult for yourself...or have it made difficult for you by an inspector!

NEC = No Electrical Consistancy

Where else can you find 33 kV at the top of a wooden pole. 11 kV a few feet lower down the pole with rusty leaky tin can transformers providing houses with 120 / 240 volt and below them telephone cables with junction boxes suspended mid span.

US double sockets are designed so they can be split on to two different circuits. You simply cut the internal links between the two.

Never seen those: have you got a link?

No worries: found them on YT...
