How can we improve Design Master?

Single-phase load on three-phase equipment

Add a way to include a single-phase load on three-phase equipment. One common use for this is VAV boxes with 3-phase heaters and 1-phase motors, all with a single electrical connection.

    The current workaround for this request is to create two pieces of equipment. Set one to be three-phase and one to be single-phase. If you are sizing the breaker and wire based upon FLA/MCA/MOCP, make sure all those settings are the same.

    Circuit the three-phase equipment first. Then use the "Circuit to Phase" button to connect the single-phase equipment to one of the phases.

    Not perfect, but it does work with the software as it currently exists if you need to handle this situation immediately.
