Electrc 2005 NEC Calculator - 2.3

Electrc 2005 is a suite of tools that performs your most common electrical design calculations in full compliance with the 2005 National Electrical Code.

Conductor sizing: Single or parallel (up to 12) conductors per phase, voltage drop, circuit type, ambient temperature and quantity current carrying conductors derating, terminal temperature factoring, 30 conductor types plus custom conductors, continuous or noncontinuous loads.

Conduit & Trough Fill: Any combination of conductors per fill calculation including bare and custom conductors, 13 raceway types plus trough, alternate raceway size option.

Motor Calcs: Motor conductor, overcurrent and overload sizing, Single or parallel (up to 12) conductors per phase, voltage drop, circuit type, ambient temperature and quantity current carrying conductors derating, terminal temperature factoring, 30 conductor types plus custom conductors, single phase up to 10 Hp, three phase up to 500 Hp.

Lighting Design: Many built-in lighting fixtures and lamps or specify your own, reflectance and maintenance factor parameters, standard and reverse lighting calculations.

Panel Directory: Print panelboard directories in two sizes (4x6 or 6x8 inch), optional footer text.

Transformer Sizing: Solve for kva rating or load amperage, primary and secondary overcurrent protection, distribution and autotransformer types.
