What is an SSU and what does it do? : It is a unit located on the side of the first which receives power (120 volts) before anything located within the furnace itself. It primarily consists of a switch and a fuse, and it is what allows for power to flow to the door switch. Opening the switch on the SSU will cut power to everything within the furnace. What is an OCPD? Describe its function in detail. : An OCPD is an Over-Current Protection Device, and it will protect conductors and equ...

Heat Pump Prep Test Graded A+ An air-to-air heat pump has many of the same components as an air conditioning system. The major difference is that a heat pump also has a ️Reversing Valve What is the difference between "demand defrost" and "timed defrost?" ️Demand defrost happens only when needed and timed defrost is based on time/temperature The thermostat that controls the auxiliary electric heat according to the outdoor temperature is called ️outdoor ambient thermostat The o...

Accelerating Power - In a GENERATOR, the difference between the MECHANICAL INPUT POWER and the electrical output POWER (assuming no LOSSES). For a GENERATOR's TORQUE ANGLE to change, the GENERATOR must have accelerating POWER. Accumulated Inadvertent - The accumulation over time of INADVERTENT ENERGY. The accumulated inadvertent account of a BALANCING AUTHORITY represents the amount of excess ENERGY a BALANCING AUTHORITY has either supplied to the INTERCONNECTION or absorbed from the I...

Heat Pump ESCO Graded A+ An air-to-air heat pump shares many components with an air conditioning system. The main distinction is that a heat pump includes a reversing valve. "Demand defrost" is triggered only when necessary based on conditions, while "timed defrost" operates according to a predetermined schedule or temperature threshold. The thermostat controlling auxiliary electric heat based on outdoor temperature is known as the outdoor ambient thermostat. The outdoor temperatur...
