Exam 11: Float Switch Control of a Pump and Pilot Lights Circuit (3), Developing a Wiring Diagram Circuit (1)

The letter "C" stands for ____________________ when labeling terminals.

In the float switch circuit, if the pump motor becomes overloaded, a(n) ____________________ stops the pump motor only.

After numbering components, connection of the circuit is made by connecting ____ numbers.

What are the rules for the numbering system used to understand circuit connections?

What happens when the circuit requires pilot devices to use more contacts than they contain?

Most pilot devices, such as float switches, pressure switches, and limit switches, usually contain more than two contacts.

In the float switch circuit, what happens when motor starter M1 de-energizes?

The method used for developing wiring diagrams is the same as the method used for installing new equipment.
