Paul will hopefully chime in here, but it looks like you have some options.
So I would assume that you will need to use 2 CTs to properly monitor a 240v load. It also looks like you could use 2 AUX channels to do this. Whether or not you can double up 240v loads to monitor 2 at once I don't know. I suspect the total AMPs would be too great on the AUX channels (they can monitor 3 15amp circuits, but that's only 45 AMPs and probably not enough for two 240v loads). But perhaps the 2nd main channel could be used in this fashion. Afterall, those channels seem to have a much higher capacity since they are designed to monitor the whole house load. That way you could monitor the whole house on channel 1, the 240v loads on channel 2 and you would still have your 5 AUX channels to monitor other loads. Of course you'll need confirmation from Brultech that this would work. :angry:
Bruletech web site said:Seven integrated power meters in one!
- Two channels with "net" metering capabilities for renewable energy installations.
- Aux channels capable of any 120V or 240V load.
- Capable of up to three 15A breakers on a single Aux channel.
- FIVE additional channels of true power energy metering (Aux1 to Aux5).
- For any of the 7 power meter channels, a 120v or 240V load may be monitored (as long as they are supplied by a common 120V/240V split-phase source. 240V loads may require a two-CT arrangement).
