what exactly is "through branch circuit wiring&quot

[jposner]

I have a bunch of newly installed 4", line voltage, recessed lights daisy chained together. The housings are NOT rated for through branch circuit wiring. Most other brands I have seen are. What exactly does this mean, and was this a bad choice? What are the restrictions of using this housing compared to a housing that is rated for through branch cirtuit wiring?

Thanks,
Jeff

Basically, a housing that is identified for through-wiring is permitted to contain conductors not assoicated with the fixture or lighting circuit. A housing not identified for through-wiring may only contain conductors assoicated with the fixtures or the lighting circuit.

Based on your description, you are permitted to loop (daisychain) between each fixture even if the housings are not identified for through-wiring.

This basic requirement is decscribed in section 410.11 of the NEC 2002

Did a truck stop about 4 years ago and we were sent a seasoned J man

If it was 18 AWG he was good to go up to 50' on a 20 amp circuit, 16 AWG up to 100'.
