The maximum current that a conductor or equipment can carry reliably without damage.
Decibel Adjusted.
Decibel above reference noise.
Direct current, or voltage.
The LCD display on the front panel of inverter system.
A ground circuit that has contact with the earth.
Operating mode by which the load is supplied directly by the AC source if it is within the
tolerances defined by the user. This mode reduces the consumption of electrical power.
Refers to an installation electrician qualified to install heavy-duty electrical components in
accordance with local codes and regulations. Not necessarily qualified to maintain or repair
electrical or electronic equipment.
