The transformer must be an integral part of the motor controller, and be located within the controller. (C)(4): Allows transformers with primary currents less than 2 amps to be protected with primary fuses at % or less of primary full-load amps. (C)(1): Allows the control transformer to be protected by the motor.

Maximum loading for any branch circuit is 80% of rating of circuit for ampacity of wire for any load. NECuse NEC for ampacity. This applies to not more than 3 phase conductors in 1 conduit.

Warning. The NEC requires that for an output voltage higher than 50 VAC one side of a control transformer secondary be connected to ground or both sides of the secondary must be fused.

True When a control transformer is used, NEC requires that both sides of the secondary must be connected to earth ground. A transformer transfers electrical energy (power) from one system to another by induction, with no physical connection between the two systems (other than grounding and bonding connections).

Thus, the National Electrical Code (NEC) refers to transformers as “separately derived systems.”. Scope. (A) Covered. This Code covers the installation and removal of electrical conductors, equipment, and raceways; signaling and communications conductors, equipment, and raceways; and optical fiber cables and raceways for the following: (1) Public and private premises, including buildings, structures, mobile homes, recreational vehicles, and floating buildings(2) Yards, lots.

In transformers and in a certain class of motors the fluctuation of the poles is not of great importance, but in another class of these motors it is desirable to obtain the theoretical result. In applying this principle to the construction of motors, two typical forms of motor have been developed.

When selecting a Transformer to feed a motor, it is important to note that the starting current of a motor can 6 to 7 times the full-load running current, or even higher if it is a high efficiency motor.

The National Electrical Code (NEC) addresses the minimum requirements to meet these needs. On the other hand, building owners are looking for ways to mini-mize the size of electrical equipment in order to accommodate more building space for productive uses, thus minimizing costs.
