Electrical Ground, Wire Size - The minimum size gec accredited to attach a concrete encased electrode is 4 awg copper. Constructing metal and metallic underground water piping that qualifies as a grounding electrode may additionally require a bigger gec for the reason that gec to these electrodes is sized primarily based on the size of the provider entrance conductors and table 250.66. It'd no longer be code compliant to run a 6 awg copper gec from the service to a floor rod, after which run a gec bond jumper from the rod to every other grounding electrode that required a larger gec consisting of a concrete encased electrode. Say, for instance, that the insulation in your hot cord gets broken and the conductor comes into touch with the metal body of your washing machine. The modern shorts via the chassis and then through the ground twine. This high contemporary causes your circuit breaker (or fuse) to ride. In case you did not have the ground wire then the mains voltage would electrify the whole chassis. Then the following person touching it becomes the return path :).
A grounding electrode conductor (gec) from an electrical service to a ground rod, pipe or plate kind electrode is by no means required to be larger than 6 awg copper or four awg aluminum until the gec keeps on from the rod, pipe or plate to connect some other electrode that may require a bigger gec together with a concrete encased electrode, building metallic or metallic underground water pipe that qualifies as a grounding electrode. Anyway, the ground wire need to most effective convey present day in the case of a fault condition. Within the usa, residential floor wires are regularly just naked, uncovered copper. While plugging in a grounded equipment or different tool, the ground cord receives attached to the chassis.
In a product with a steel chassy, the chassy is commonly grounded. If there had been simplest two traces then the chassy would be attached to neutral. In the event that the new and impartial were swapped the chassy could be electrified. Fridges, stoves, ovens, dishwashers are just a few matters that use this device.
