daisy-chain 2x4 lay-ins

[prs1029]

I know we use to be able to daisy chain 2x4 lay ins in 300.15. But I heard rumer that this was no longer acceptable. Is this true or are they making up codes again?

That's the requirement for the discos in each fixture... nothing to do with daisy-chaining.

Ken,

I know......there is not a requirement for daisy chaining loop in loop out of switch leg....to my knowledge. I simply pointed out to the op that disco means are now required.

Definitely a made up code.

However, I think regional practices may have something do with this rumor. I know that in other parts of the country it's very common to run an EMT with a j-box to each light location and then run a whip down to each light.

Here in New England we almost always daisy chain with MC cable unless it's spec'ed otherwise.

We see quite a few daisy chains using the 18 ga whips that come with the fixture and of course that is not allowed.

Eh?!? What'd you say, sonny?

240.5(B)(2) permits the use of #18 fixture wire in lengths up to 50' to be protected by a 20A OCPD. If the total wire length of the conductors in the whips is 50' or less, the code would permit daisy chaining.
