Daisy-Chained Panels

[jmcooper]

I have a some daisy-chained panels meaning one panel feeds another so that they are chained like this: Main Panel > Outside Panel > Inside Panel. See below for a better description of my setup. I plan to install a Vue (with expansion) in the Outside Panel AND the Inside Panel since they both have individual circuits I want to measure. But since the outside panel has a breaker that feeds the inside panel, my question is: If I connect the large clamps to the mains in both the outside panel and the inside panel, will it report double the usage for the inside panel since it is powered from the outside panel where the mains are being monitored in addition to the inside panel’s mains being monitored? Should I not install the large clamps around the mains in the inside panel since that energy is already being monitored, presumably, by the outside panel?

This same question applies to installing two Vues inside the same panel in order to monitor more than 8 circuits with two expansions. Should both Vue units in that panel be attached to the mains or would that cause it to report double the usage?

 

Main Panel

• Outside Panel (2 * 100A breaker)

Outside Panel

• Inside Panel (2 * 100A breaker)
• EV Car Charger (2 * 70A breaker)
• Oven (2 * 50A breaker)
• AC Unit 1 (2 * 30A breaker)
• AC Unit 2 (2 * 30A breaker)

Inside Panel

• Lots of 20A and 15A breakers

I have a similar setup and questions. At the very least, I would like to be able to relate the two Vue’s in the app so that the ‘Main’ Vue knows to subtract the ‘Sub’ Vue’s usage from the Balance. In my case, I cannot monitor all of the circuits in either panel, but I know that the ‘Sub’ panels usage is being double counted and included in the Balance for the ‘Main’ panel.

Vue #1 – Main Panel (primary clamps on service line in):

• Furnace – Primary (15A)
• Furnace – Secondary (15A)
• Kitchen Refrigerator (20A)
• Kitchen Lights/Outlets (20A X 2) – grouping two circuits together in one clamp
• Clothes Dryer (30A X 2) – using multiplier to represent dual breaker
• Garage (20A)
• Basement Lights (15A)
• Basement Utility (15A) – Water Softener/Chlorinator/Hot Water Cycle pump
• Sub Panel Breaker (100A X 2) – not connected to Vue

Vue #2 – Sub Panel (primary clamps on leads from Main Panel):

• Kitchen Cooktop/Oven (30A X 2) – using multiplier to represent dual breaker
• Kitchen Wall Oven (30A X 2) – using multiplier to represent dual breaker
• Kitchen Wine Fridge (20A)
• Kitchen Dishwasher/Disposal (20A)
• AC – Primary (60A X 2) – using multiplier to represent dual breaker
• AC – Secondary (25A X 2) – using multiplier to represent dual breaker
• Septic Lift Pump (20A)
• Well Pump (20A X 2) – using multiplier to represent dual breaker
