Yes, it is necessary to attach the bare equipment grounding conductor of a nonmetallic-sheathed cable to the green hexagon-shaped grounding screw on a receptacle. This connection ensures proper grounding, which is essential for safety by preventing electrical shock and reducing the risk of electrical fires. Proper grounding also helps protect equipment and improves the overall reliability of the electrical system.
It allows for a separate equipment grounding conductor
Yes, a GFCI receptacle can be installed as a replacement in an old two-wire circuit without an equipment ground conductor. When doing so, the GFCI will provide ground fault protection, but it must be labeled as "No Equipment Ground." However, it's important to note that while the GFCI protects against ground faults, it does not provide a true equipment ground, so care should be taken when using appliances that require grounding.
No. To prevent this sort of thing from happening, the 277 volt device and receptacle is physically larger that a 240 volt receptacle and will not fit in a regular receptacle junction box. For a 277 volt system the proper size junction boxes have to be purchased.

This connection ensures that the grounding system is properly established, providing a safe path for fault currents and reducing the risk of electric shock. Proper grounding enhances the overall safety of the electrical system by preventing electrical hazards.

The equipment grounding conductor chart provides information about the size of the conductor needed to safely ground electrical equipment based on the current rating of the circuit.
The equipment grounding conductor table provides information about the size of the grounding conductor needed based on the type and size of the electrical equipment being used.
Actually, yes. The GFCI does not need any ground; it measures "leakage", i.e., an imbalance, regardless of whether there is "ground". The National Electrical Code permits installing a GFCI to replace a completely ungrounded receptacle. Others have said: No. The GFCI is designed to measure an unintended path to ground. Without a good ground reference this is not possible.
electrical receptacle
Most of the times yes. If it is an appliance that gets pulled out of a receptacle under load and there is a small arc produced this will not damage the receptacle. It will pit the blades inside the receptacle but not enough to render the receptacle unserviceable It is not recommended to use this method to disconnect electrical equipment, use a switch in the circuit as they are designed to open a circuit under load.

The maximum amperage rating for a 60 amp receptacle is 60 amps. Appliances or equipment that typically require such a high amperage capacity include large kitchen appliances like electric stoves, ovens, and clothes dryers. Industrial equipment such as large motors and machinery may also require a 60 amp receptacle.
