The size of a control transformer can be determined by adding the power requirements of the components in the control circuit.

Before selecting a control transformer, it is important to consider the ___ of a circuit.

A buck-boost transformer cannot be wired in an open delta when the load is relatively low to buck the voltage from 240 V to 208 V.

During a fault condition with an open circuit on the secondary side, anyone coming in contact with the secondary may be exposed to the full ___ voltage.

___ is found by multiplying the voltage and the current.

Motors are rated to operate at 10% above or below the nominal voltage.

The method of sizing a transformer by calculating the load power can only be used when the buck-boost transformer is wired as a(n) ___ transformer and the entire load goes through the transformer secondary.

It can be difficult to determine when a control transformer is undersized because most troubleshooting measurements are taken when all or almost all loads in a circuit are ___.

Voltage can be boosted from 208 V to 228.8 V to supply a 230 V load.

A(n) ___ system is required to guard against single-phasing or internal faults in 3-phase, 4-wire systems.
