    Correct

    As long as your power source is coming from the same house or building Main breaker, your on the same source. Electrical wiring 101. A neutral wire connected or not has nothing to do with equipment grounding or loops. The green or green / yellow wire connected to the ground buss at the main panel is the only equipment ground. This is basics folks. The real electricians in the group understand, you do not. I will no longer post on this Thread but will let the electricians have a good laugh on your answer above.

    The laugh is on you I did not post that

    Now you are posting posts under my name that I did not post, you are really messed up, your link has nothing to do with this thread, I'm not sure what you are trying to commutate here but you are failing to understand what is being posted

    For those that don't understand what a Ground loop is here is an basic explanation of what a Ground Loop is a snip below is a common one with home connections, the same applies with machines as well

    Ground Loop Basics

    What is a Ground loop ?

    A Ground loop occurs when there is more than one ground connection path between two pieces of equipment. The duplicate ground paths form the equivalent of a loop antenna which very efficiently picks up interference currents. Lead resistance transforms these currents into voltage fluctuations. As a consequence of ground-loop induced voltages, the ground reference in the system is no longer a stable potential, so signals ride on the noise. The noise becomes part of the program signal.

    Ground loop is a common wiring condition where a ground current may take more than one path to return to the grounding electrode at the SERVICE PANEL.

    Question Re: 110v VFD's. Any issues?

    I wanted to have a power shut-off switch right before my 240 volt receptacle so that I could unplug it safely.

    I'm pretty sure this one would work but just wanted to be sure before I order it;

    Or would I use this one, it's a Double - Pole, Single Phase version;

    Yes you only need the double pole for your install your 240v install, at the wall a switch is nice to have but not needed if you have a disconnect at the machine
