Is it acceptable to run the voltage input for an emon dmon off the same breaker that the emon dmon is monitoring if it is a high amperage breaker?

For instance, lets say I am monitoring a 100 amp breaker with an emon dmon. The terminals for the input voltage of an emon dmon are rated for max #10 wire. The breaker I am monitoring is a 100 amp breaker. Can I run #10's off the 100 amp breaker to the input voltage of the emon dmon if it is less than 10 feet away? Does it fall under the 10' tap rule?

I know the ideal would be to come off a 20 amp breaker of the same panel, but if the panel is maxed out, is this acceptable knowing that the emon dmon will only draw so much amperage?

Thanks
 
It does not matter what breaker supplies the voltage to the emon. The voltage only has to come from the same source as the current it is monitoring. You can feed the emon from a 100 amp breaker but I would put in line fuses like IWire said. Emon probably has a max breaker size anyway.

I have not used emon, but I used a bunch of EKM meters. Nice system and much lower cost than emon FWIW. Anyway, they spec'd I think a 2 amp fuse for the voltage lines. I have seen some emon's installed and they always had a fuse. As far as code goes, its definitely not a feeder so those tap rules dont apply. Its a factory UL device so generally I would say they are not NEC conductors. I think its a 110.3(B) issue.

What the heck is a "Emon Dmon"?

Sounds scary!:huh:

I have been meaning to get back to this.

ok yes sloppy wording. Let me try again: The voltage lines to the emon are not feeder taps.

If I connect a emon demon to a 100 amp breaker as the OP is talking about IMO those emon demon leads would likely be feeder taps.

Also The conductor supplied by the breaker is not necessarily a feeder.

It is possible that the 100 amp breaker is branch circuit but we both know the chances are much higher it is a feeder.
