Design Master Electrical RT

Sunday, September 1st, 2013

Design Master Electrical RT is out of beta and now officially available for purchase.

The software expands and improves the electrical calculations available in Revit MEP. Calculations include branch circuit breaker and wire sizing, feeder sizing, fault, voltage drop, and arc-flash. The engineer is given control over all the parameters of the wires to allow the calculations to be as accurate as possible. All calculated values can be override as necessary for the final design.

Branch Circuit Breaker and Wire Sizing

Branch circuit breakers are sized automatically based upon the load connected to the circuit. The wire size for the branch circuit is based upon the calculated breaker size.

Individual circuit breakers can be resized as needed when the calculated value is not appropriate.

Individual wire sizes can be resized to account for voltage drop and other design situations.

Feeder Sizing

Feeders are sized automatically based upon the rating of the overcurrent protection for the electrical equipment. You can control the default feeder size based upon the ampacity of the wire.

Individual feeders can be customized as needed. Upsize a wire based upon voltage drop or choose to use aluminum for a specific feeder to cut costs.

A schedule of all the feeder sizes can be created and viewed in Revit MEP. It lists each piece of electrical equipment in the project and the corresponding feeder size. The electrical equipment is grouped by the ampacity of the upstream OCP.

Voltage Drop

The voltage drop calculations use the feeder sizes set using Design Master Electrical RT.

Feeder lengths are calculated by Revit MEP based upon the position of electrical equipment in the model. You can override the length of specific feeders when the calculated length is not correct.

A schedule of the voltage drop on each feeder can be created and viewed in Revit MEP. Voltage drops that exceed 3% are highlighted in the schedule, showing you where you need to upsize your wires.

Fault Calculations

Feeder lengths are calculated by Revit MEP based upon the position of electrical equipment in the model. You can override the length of specific feeders when the calculated length is not correct.

A schedule of the fault current at each piece of equipment can be created and viewed in Revit MEP. Fault current that exceeds the AIC rating for the equipment is highlighted in the schedule.

Arc-Flash

A schedule of the incident energy and required PPE at each piece of equipment can be created and viewed in Revit MEP.

Warning labels listing the required equipment specifications and energy values can be printed.
