Maximum number of feeder taps

[Zorak]

Is there a limit to the number of taps that can come off the same set of feeder conductors?

We are wanting to run about 12 motors, most of them around 1 HP with the largest being 7.5 HP. All are 480V 3P.

I would like to run a single feeder from a disconnect to a gutter and tap off for each motor with a starter or VFD directly below the gutter, thus taking advantage of the 10 foot tap rule.

However, for some reason, gnawing at the back of my head, I seem to recall that there may be a limit on the total number of taps made on a set of conductors (as long as the feeder conductors are properly sized for all the tapped loads).

I have not yet found anything saying so in the NEC but it is an area I do not frequent much. So, is there such a limit or am I having phantom memories?

Any help is appreciated.

Thanks.

To my knowledge, no limit om quantity as long as the all meet the appropriate 240.21 section.

There is no limit. If there were, it would be early on within 240.21. Welcome to the forum.

Thanks for the information. I cannot say why but somewhere in my head, the number 9 was floating around. But no limit, as long as the feeder is properly sized and protected will work great. And it will be according both the tap rule and the requirements of feeder taps for motors.

Charlie, thanks also for the welcome. I've been around since 2006, but as a lurker.

Thanks again for your help.
