BreakerWiring is a plugin for Autodesk® Revit® that expands the electrical work based on NEC NFPA 70 standard:

-        Feeders and branch circuits calculation: The plugin allows to discern what type of circuit is, and calculates in a different form.

-        Overcurrent protection devices of each circuit: The plugin has a parameter that the user can change manually and control the Rating according to NFPA standards.

-        Voltage drop: Data percentage of voltage permissible drop: 0.5 % to 5 %, it can be manually change by the user and this calculation can be done individually per circuit or takin in account the upstream circuits.

-        Conductor coordination with overcurrent protection device: The plugin has the correction factors of temperature and group for conductor calculation and coordination with de overcurrent protection device rating.

-        Wire sizing: According to the load of the circuit, for panelboards circuits it can be used the Estimated Demand of Autodesk Revit or the demand calculation of the addin.

-        Conduit sizing: According to the AWG of the circuit.

-        Electrical circuit creation for calculations.

The plugin associates several shared parameters to the category of electrical circuits:

Calculations window: Data that are assigned to the electrical circuits and electrical equipment:

-        Wiring: Select the type of wire according to copper or aluminum and isolation.

-        Temperature: Select the temperature range to assign the temperature factor to the circuits.

-        Voltage drop: Value 0.5% to 5%, to voltage drop calculations.

-        Type of voltage drop analysis:

Individual circuit: The nominal voltage of the circuit is used as the voltage start.

Circuits+Feeders: The voltage used as voltage start will the value taking in account the voltage drops of the upper wiring.

-        Minimum breaker for circuits with lighting fixtures: It can be 15 A or 20 A.

-        Minimum breaker of circuits without lighting fixtures: It can be 15 A, 20 A or 25 A.

-        Length Circuits:

Length Revit default: The addin will used by default the length of the electrical circuit that Revit calculate or the user change.

First run per circuit: The addin will assign the value of the length calculated by Revit, then this value can be changed manually by the user.

-        Checkboxes:

Update: Update all the data according to the entry data of the window, if this is off, the circuits will remain data as type of conductor, voltage drop, minimum breaker and derating factors

Neutral for 2 phases loads: Add neutral conductor for electrical circuits of 2 phases.

Neutral for 3 phases loads: Add neutral conductor for electrical circuits of 3 phases.

The Calculate button assigns to the aforementioned shared parameters the corresponding values according the electrical calculations.

If the user creates a new electrical circuit the shared parameters will be empty, so the plugin must be run.
