Ayrton

A point that is used as a common connection for other parts of a circuit is called a blank point

Chassis

There are six current carrying conductors in a raceway that is to be installed in an area with ambient temperature of 90°F. It is necessary to blank

Correct for temperature and derate

An increase in blank, not resistance, results in an increase of load

Current

In Series circuits, the blank is the same at any point in the circuit
