Voltage can be continuous (Direct Current or DC) or alternating (AC). The frequency of alternating voltage is the number of times per second that it changes polarity from positive to negative. Most power voltage in the US is delivered at 60 Hertz (60 changes from positive to negative per second).

An electronic device that allows only certain frequencies to pass. Zero Surge uses a low pass filter which means that our filter allows low vibrating power to pass through unimpeded while stopping higher frequency vibrating power. Unlike filters for liquids, electric filters that Zero Surge uses never needs to be replaced.

A fault is a wiring problem such as a broken wire (open circuit), or wires touching (short circuit) typically due to storm damage, requiring physical repair.

Proof that a product has been independently tested by Intertek and meets the applicable published North American safety standard. ETL stands for "Edison Test Lab" - yes, that Edison!

Energy (expressed as joules or watt-seconds)

Property that is a measure of transferring work onto an object. There are many forms of energy. In electricity, energy is how much power is consumed over time. The standard unit is joules which equals 1 watt-second. For example: A 60 watt light bulb turned on for 1 second expends 60 joules of energy.

Electro-Magnetic Interference (EMI)

Electrically induced noise or transients

Undesirable performance changes.

Current (expressed in amperes or amps)

Current is the electrical flow of electrons. Current will flow in a circuit when the applied voltage exceeds a certain level, as dictated by the various components in the electrical circuit. Flowing water in a hose is a good way to think of current flow.

A voltage on the neutral wire of the power wiring, when compared to the ground wire, where the ground wire is assumed to be the reference.
