Editing Circuits
Branch circuit breakers and wire sizes can be set automatically based upon the connected load of the branch circuit.
On new projects, the breaker sizes for newly created devices and circuits will be set to Size automatically. They will be sized based upon 125% of the connected load of the branch circuit.
To override breaker sizes for branch circuits, use the Circuit Edit command. This command allows you to set specific breaker and wire sizes. This functionality is useful when you need to adjust a breaker size for a piece of equipment or the wire size to account for voltage drop.
The branch circuit breaker size uses the Revit Rating parameter value for the circuit. This parameter is typically displayed in your Revit panel schedule.
The branch circuit wire sizes use custom shared parameter values. You must manually modify your panel schedule to display these values. See the Modifying Panel Schedules section for more information about how to make these values appear.
Calculating Circuit Breakers in Current Projects​
On projects for which devices have already been inserted and circuited, the first time you run the Calculate Whole Project or Calculate Part of Project command, breakers for branch circuits and feeders will be sized as though they were set to Size automatically unless otherwise configured using ElectroBIM commands. Any breaker sizes that had been manually changed in Revit without using ElectroBIM may be changed, which can impact wire sizing, voltage drop calculations, and other parts of the design.
After the calculation finishes, ElectroBIM will create and display the ELECTROBIM CIRCUIT VALUE COMPARISON schedule. This schedule shows any circuit for which the Revit Rating parameter changed during the calculation. Additional information is provided to help you find each circuit.
The schedule will continue to be displayed each time you run the Calculate Whole Project or Calculate Part of Project command. If you no longer need the schedule, you can delete it to stop having it displayed.
