I pulled this from the Leviton URL:


Couples transmitter (programmer and controller) signals generated on the 120V leg where the transmitter draws power into the other leg in a 120/240V system or any phase of a 3-phase 120/208V residential wiring system. Pilot light indicates DHC signal is transmitting. Use cat. no. HCA02-10E in installations requiring Intellisense niose immunity.
Note:A system amplifier must be installed in all panels in every DHC installation to ensure adequate signal strength.

I hope this helps!

Timothy,


That is part of a Leviton Decora Home Controls (DHC) system. Here’s a link to a .pdf brochure on the system that you can print if you like.

I don’t see the required 2 pole OC protection for this device. Was it there?

Michael,


Good point. I never examined the SE wiring while looking at this device. It appears to be improperly double tapped at the main lugs.

It definitely needs OC protection from a dedicated SP or a 2 pole circuit breaker.

Good Eye.

Was that equipment permitted to be in the cabinet?


What do the instruction's say?

Isn't it a 3 phase unit? ![icon_question.gif](upload://t2zemjDOQRADd4xSC3xOot86t0m.gif)

I thought all this stuff was supposed to be on the outside of the cabinet.

I agree with Joe. icon_biggrin.gif I must be learning something.


1) Very unlikely this is approved for mounting in the panel

2) No overcurrent protection

3) Miss use of the lugs. / double tapping.

4) 3 phase 208 equipment used on a 240 volt single phase supply.

By the way did anyone notice all the NMs are coming into the panel through only two entries?



It is a common method in some areas.
