It is terminology used in the telephone industry in regards to when a telephone circuit is activated when the handset has been lifted from the cradle or off hook. Off hook comes from when telephones had separate receivers that you put to your ear to listen. It was hung on a hook device on the side of the telephone. The mouth piece was fixed stationary on the front face of the telephone and the whole telephone was mounted on the wall.
To hook up a 40 amp breaker panel, first turn off the main power source. Then, connect the wires from the circuit breaker to the panel's bus bar, making sure to follow the manufacturer's instructions. Lastly, turn the main power back on and test the circuit to ensure it is working properly.
In a lighting circuit an open circuit will turn off the light.
A switch is a device that can be used to turn a circuit off and on. When the switch is in the "on" position, current can flow through the circuit, and when it is in the "off" position, the circuit is broken and current cannot pass through.
The on and off switch controls the flow of electricity in the circuit. When the switch is on, it completes the circuit and allows electricity to flow through. When the switch is off, it breaks the circuit and stops the flow of electricity.
A switch makes a physical break in the electric circuit. With the circuit broken the electricity can not flow. When the switch is turned the other way the circuit is completed and the current/electricity can flow.
usually a "night security light" just means that the light is on a circuit that does not get switched off at night.
