This is usually seen as a good move, given the fact that additional revenue streams become available without excessive overhead or investment during uncertain economic times.
Overcurrent devices provide an essential level of protection in residential, commercial, and industrial applications. Flawless functionality, however, is dependent upon correct design and installation.
Proper grounding and bonding prevent unwanted voltage on non-current-carrying metal objects, such as tool and appliance casings, raceways, and enclosures, as well as facilitate the correct operation of overcurrent devices.
