Circuit Breaker – is really an immediately operated electrical switch created to safeguard an electrical circuit from destruction due to overcurrent/overload or shorter circuit.

Triple Issue – the temperature and tension where stable, liquid and vapor refrigerant can coexist in equilibrium. Animated image demonstrating triple level.

Magnehelic – Model name of the gauge built to measure tension drop - generally across air conditioning filters. Image one

Industry – a area wherever magnetic traces of pressure may be detected from a magnet or electrical circuit.
