The voltage rating is a function of a switch's ability to suppress the internal arc that occurs when a switch's contacts open. One horsepower (1HP) is also equal to 746 watts of electrical power. Motors are rated in horsepower (HP) or fractions of horsepower (1/4, 1/3, 1/2, etc.) Mechanically, one horsepower (1HP) is equal to 33,000 pounds being moved 1 foot in 1 minute (or 33,000ft-lb/min). Voltage is also called electrical potential, because if voltage is present in a conductor, there is potential for current flow. Voltage itself does not flow through conductors, but is the force that causes current to flow. The electrical pressure necessary to cause this movement is voltage. The flow of electrons through an electrical conductor is called electrical current, which is measured in amperes or amps. Carling Technologies switch ratings are listed by amperes, volts, and horsepower (when applicable).Įlectricity is the movement of electrons from one atom to another. Any Carling Technologies' switch that has agency approvals will have its ratings stamped on its base.
