NCCER Electrical Level 3 Module 11
'Motor Controls'
If the heater in a hard and fast IEC bimetallic overload relay fails,
the entire overload relay must get replaced
The nameplate of a motor indicates that the motor has an FLC of 15A and a carrier element
of 1.15, how a whole lot extra modern can this motor effectively handle for intermittent
electricity demands?
15A(1.15)= 17.25; 17.25A - 15A= 2.25A
The minimum allowable coil manage voltage needed to maintain an electromechanical
device energized is known as the ___.
Seal-in-voltage
A fashionable motive NEMA enclosure is ___.
Kind 1
NEC Article 430, Part VII covers ___.
Motor controllers
What describes a retro-reflective test?
The scanning technique in which a target is detected as it passes between a photo electric
sensor and a reflector
If a responsibility cycle consists of extensive plugging or strolling, select an ___.
AC-four rated motor manipulate tool
Jogging is also referred to as ___.
Inching
Most brief suppression modules include an RC circuit this is designed to suppress coil
voltage transients to approximately. What percentage of the peak coil deliver voltage?
Two hundred%
