Re: 2/120v in same box
With two 120 devices, would the maximum voltage be more than 300V if they were on L1 and L2?

Re: 2/120v in same box
i appreciate the answer Roger.
Mr baker, I don't think it can be more than 240V. 2x120 if on L1 and L2 and 0 if both on L1 or L2. it's a typical residential wiring. my problem with the wording of 404.8 is that it state SNAP SWITCHES adjacent to other devices..
Thanks again

Ace-where this rule applies is for 277V lighting circuits. A slight wording change for the 02 NEC clarified it could be any two adjacent devices, not just snap switches.
