Each box has controls that add up to 20 VA. Each box has a 40VA transformer, 120v to 24v. How do I calculate how many VAV boxes can go on a 20 amp 120 volt circuit?
Is It Good To Use One Circuit For One Junction Box Or Is It Good To Go With Multiple Junction Boxes? Using one junction box for multiple circuits saves space. However, multiple junction boxes make more sense. You have two significant issues: 1). Safety. Lighting, Light Fixtures, Ceiling and Exhaust Fans - Can I branch out multiple wires from a junction box? - Can I have one main power source where I connect 2 other branches to separate circuits. All inside a junction box. In other words, 1 source turns into 2. I believe I would just connect live to live, neutral to How many junction boxes can I have on one circuit? There are no limits on the number of junction boxes (without devices) in any particular circuit. Each piece of ‘utilization equipment’ reduces the maximum allowable load by it nameplate rating, 180va for each receptacle, and each light fixture at its maximum labeled lamp wattage.
One circuit had 24 outlets and another had 18. I ran three more home runs into the attic and split them up so no more than 10 outlets were on one circuit. . It may be possible to leave the existing wire in the walls and use junction boxes to tie into them. 12-2 wire is about 80 to 90 dollars for 250'. Depending on height of walls, where . The two breakers should be ganged together, so that if one trips, both will trip, and all junction boxes in the circuits become deenergized. The two hot leads from the power panel (two black, or one black one red) MUST be wired to opposite legs (one to L1, the other to L2).Sure, but the Combiner is really a great piece of equipment to have; anyways, you can have 1 microinverter in a branch circuit.

The number of fluorescent lights that can be on a circuit depends on the circuit’s amperage and the wattage of the fixtures. For example, A 15-amp circuit can handle up to 12 amps, which means you can have up to 8 40-watt fluorescent fixtures on a single circuit. One may use this table to determine the safe wire capacity for junction boxes. For example, how many 12 wires in a junction box? If it is a square box with the dimension of (4 X 1 1/4) inches, then 9 wires of size 12 can be fit in the box.

The load probably wont exceed 5 amps, and with the general use of low energy lamps is unlikely to exceed even half that.
@ThreePhaseEel The box will house : 2 4-way dimmers, 1 single pole dimmer and 2 duplex receptacles.
