What is maximum power rating?
Maximum power rating describes the maximum power at which a device can operate without reaching an excessive temperature. For example, in the case of a resistor, if its maximum power rating is exceeded, then it may burn out.
When grounding a metal box what must be done?
The grounding system of a distribution must be from zero ohms to a maximum of two ohms. This is usually obtained by bonding all metallic parts back to the distribution centre with a wire capable of handling the circuits fault current if the circuit should ground out. The ground wire in cable sets is used for this purpose.
