Magnetic type overload relays are sensitive to ambient temperature.

High voltage surges are harmless and cannot damage electronic components connected to the power line.

Protection can be placed on the primary or secondary side of the control transformer.

Starters that are intended to protect motors that operate on 240 volts should contain four load contacts.

Many industries prefer to ground the control system and it is a very common practice.

Magnetic control systems generally operate on 240 volts.

Manual push button line voltage starters are manufactured with two or three line voltage contacts.

The most common coil symbol used in schematic diagrams is the ____________________.

Fuses and ____________________ are designed to protect the circuit from a direct ground or short-circuit condition.
