Panel is a 200 amp normal North American Panel (120/240V)
My heating system have the following component
1x Heat Pump (30 amps) Double Breaker
1x Boiler (100 amps) Double Breaker
2x Circulating pump on a single breaker (15 amps)
1x Control panel on a single breaker (15 amps)
1x Furnace (no heating coil, only fan) on a single breaker (15 amps)
I plan to use
1x 100CT for Boiler
1x 50 CT for Heat Pump
The issue is the Pump/Control Panel/Furnace, I would like just one reading for all 3, so should I use 3x 50 CT merge into 1, or use only 1x 50/100CT and pass the 3 cables through the same CT.
What would be best?
Is there a limit of the amount of CT that can be merge using Y cable?
Is there a limit of the amount of cable that you can run through a single CT?
Thank
