Understanding Motor Branch-Circuit Overcurrent Protection Devices

The primary intent of this discussion is to explain how overcurrent protection devices are determined for single motor branch-circuits. References will be taken from the 2020 National Electrical Code (NEC). These references will apply to general single motor applications for a continuous duty NEMA Design B energy efficient motor, unless otherwise noted.

2020 NEC Changes to 430.122 Conductors – Minimum Size and Ampacity

Changes to the 2020 NEC include the addition of several paragraphs in section 430.122. These changes will help the user to determine the correct ampacity for conductors used with power conversion equipment. The Adjustable Speed Drive is one type of power conversion equipment that provides a means of adjusting the speed of an electric motor, 100. A Variable Frequency Drive, VFD, is an adjustable speed drive that controls the speed, the RPM, of a motor by controlling the frequency and voltage supplied to a motor. The changes made in 430.122 Conductors – Minimum Size and Ampacity apply to Adjustable Speed Drive Systems.

How To Apply Ohm’s Law

Electricity operates within predictable boundaries. We have come to identify these boundaries as Ohm’s Law. Ohm’s Law was developed as a means of explaining how electricity operates within a closed circuit. The Ohm’s Law formula helps to communicate the relationship between different properties within an electrical circuit. We can use Ohm’s Law to explain what has occurred, as well as what will occur, when certain conditions are imposed upon an electrical circuit.

Required Receptacle Outlets for Meeting Rooms – 2017 NEC 210.17

The 2017 NEC now requires meeting rooms measuring 1,000 square feet or less to be equipped with 125-volt 15 or 20 ampere receptacles. This new requirement will help serve today’s trend that requires we travel with a myriad of electronic devices to meet our daily personal and business needs.

This new Code-reference, 210.71 Meeting Rooms, is found in Article 210 Branch Circuits, Part III. Required Outlets, and is only applicable to meeting rooms or areas measuring 1,000 square feet or less. The qualifying room or area is to be determined by measuring wall-to-wall space, as well as space created using movable partitions.

Fixed Cabinets Equipped with Countertops are Considered Wall Space- 2017 NEC 210.52(A)(2)(1)

The NEC underwent some big changes in 2017, including the redefinition of wall space, when it comes to fixed cabinets installed along a wall space. Prior to 2017, a cabinet affixed to a wall in a bedroom, den, library, etc. simply broke that wall space into two separate wall spaces. The measurement along the wall ended once you reached the fixed cabinet, and a new measurement began at the other end of the cabinet – but not anymore!

Combination Arc-Fault Circuit-Breaker VS. Dual Function: Arc-Fault/GFCI Circuit-Breaker

A “COMBINATION” Arc-Fault Circuit Breaker is NOT equivalent to a “DUAL-FUNCTION” Circuit Breaker. With ever changing electrical Code requirements, a circuit breaker with the ability to provide both Arc-Fault protection as well as Ground Fault (GFCI) protection was long overdue. But beware, the “combination” function that is identified on recently […]
