Dedicated Circuits

A dedicated electrical circuit has power and ground wires that are designed for use by a single appliance. Furthermore, the wiring for a true "dedicated circuit" must run in it's own conduit from the main electrical distribution panel to the appliance.

An isolated safety ground is a fully insulated wire that never touches any part of the conduit or any “noisy” electrical ground connection from the main electrical distribution panel to the appliance.

The purpose of these specialized circuits is to keep a very stable, well regulated supply voltage for the desired appliances to run correctly. Common uses of dedicated circuits and isolated safety ground systems are for appliances that require an extremely consistent supply of power or need to have no interference from other noisy electrical circuits.
