No, there is another barrier you have to be concerned with. That was the reason for the ?continuous or non-continuous? question. Do you know what that other consideration might be?
No. There is no specific requirement that is written in that context.
No, I don?t think so. You are looking at the situation backwards.
Then you get to make the choices. For my part, most of the lighting circuits I have designed have been 20 amp circuits. A few have been 30 amp circuits. I have never yet come across a 50 amp lighting circuit, but perhaps other members have. And as we see you can?t go over 50 amps in this application.
Well there is, indirectly, if your ocpd is less than 50A. How many lamps you can place on the circuit is limited to the circuit rating divided by 125% divided by the current rating of each lamp [fixture... meaning, especially in the case of non-incandescents, that it is stipulated by the fixture's current rating, not the lamp rating].
I'm waiting for you to tell me... 'cause my brain isn't registering any other method of calculation right now.OK. That's how I got the answer of 20. Now how did I get the answer 19?
My answer would be 19, but I suspect from the wording of the question that the person who wrote the question is looking for the answer of 20. Now, show me your work, and what answer you come up with, and then I'll tell you how I came up with those two possible answers.
First, he gets a check from the customer to set the budget. Then he buys a panel & #lights that fit in the budget. Then he installs the equipment, then the customer can decide what kind of work they can do in that area based on how many lumens they get. :grin:
Yep, that's it. If power factor were a player, the number of lamps would be fewer still.
Calculate the load. You fell into your own trap. Which make me happy
