Abstract
An apparatus supplies AC power to a load. The apparatus includes a set output terminals, a primary circuit, and a load sensing circuit. The primary circuit is electrically coupled to a source of AC power and to the output terminals for selectively providing power at a low voltage at the output terminals or electronically coupling the source of AC power directly to the output terminals. The load sensing circuit coupled to the primary circuit and the source of AC power for determining a resistance associated with the load at initial application of the load and controlling the primary circuit to electronically couple the source of AC power directly to the output terminals if a proper load is detected.

A circuit for use with a power circuit for selectively providing power, comprising:
- a switching circuit coupled to the power circuit;
- and
- a sensing device coupled to the switching circuit for sensing a parameter associated with the power circuit, the switching circuit for comparing the parameter with a predetermined condition associated with the parameter and responsively cutting off power using the switching circuit if the parameter meets the predetermined condition.
A circuit for use with a power circuit for selectively providing power, comprising:
- a switching circuit coupled to the power circuit;
- and
- a temperature sensing device coupled to the switching circuit for sensing a temperature associated with the power circuit, the switching circuit for comparing the temperature with a predetermined acceptable temperature range and responsively cutting off power using the switching circuit if the ambient temperature is outside of the predetermined acceptable temperature range.
