Fluorescent Fixtures

[erickench]

Hi Guys, here's another doozy of a question from that PassBook I'm using.

In the installation of fluorescent fixtures, the maximum number of single or two-lamp type auxiliaries which can be placed on any single fifteen-ampere branch circuit is

A. 10
B. 12
C. 15
D. 18

There doesn't seem to be any references in the NEC to determine the actual number of auxiliaries. What do you guys think?

D:grin:


It depends on the load that each fixture creates.

Don't exceed 80%

Unfortunately this question doesn't provide that information. I would have assumed that each auxiliary would be one amp and submit 'B' as the answer. But the answer key gives 'C' instead.

I knew i got it wrong.:roll:

Its a BS question because it does not state the ampacity of the auxiliaries.
BTW, what the heck are auxiliaries?

Consider this a multible guess question.

Does it even state the size of the lamp? T-12 48", T-8 48" what about 96" lamps, HO lamps?

WOW, What a guessing game, and I thought test around here were bad.

"B" only if continous, "C" if not?

It doesn't even mention 120 or 277 and that alone changes answer by more than a factor of 2.

It's a lighting load so it would have to be continuous.

No, don't go into a test thinking that.
