[QUOTE="Tim McCulloch, post: 24690, member: 67"] Re: When L21-30 just isn't big enough The difference between multiple, single leg connections and a connector or wiring device with more that ONE hot leg is exactly that. In your example, EACH hot leg is protected, but there is only one hot leg per connector or wiring device. Code requires common trip for circuits that present more than one hot leg in a connector or wiring device. It's a life safety thing to prevent a person from being electrocuted while performing trouble shooting or service. The idea is that ALL hot conductors for each circuit open together. If you don't grok that concept I'm not sure how else to explain it other than referring you to the Code itself... and I'd suggest you begin with NEC Chapter 2 and Chapter 3. [/QUOTE]
