Overloads are not a fault condition, overloads happen when there is excessive current in the circuit. An overload is where the current is more than the equipment ampere rating and the overload may result in overheating and damaging equipment. Overload protection does not protect against short-circuits or ground-fault currents. Part II of Article addresses the general requirements for system grounding and bonding of alternating-current systems to be grounded.
The size of the main bonding jumper is determined in accordance with Table The provisions of Article apply to the installation and wiring methods of storable or permanently installed swimming pools, hot tubs and spas, and to their metallic auxiliary equipment, such as pumps and similar equipment.
Article applies to air-conditioning and refrigeration equipment and to branch circuits and controllers for the equipment. The rules regarding the use and installation of rigid metal conduit RMC are found in Article As per Section Article contains installation and other requirements for generators.
