I'm putting together a belt grinder and need to wire the vfd and motor for power. This is definitely out of my wheelhouse, but I didn't think just wiring the power cord would be too difficult. So, I have single phase 220v coming from the outlet, going to the vfd, then to a 3 phase motor. Looking at the vfd manual, it looks like there are three wires coming in (S or R, T, and ground) and four wires going to the motor (U, V, W, and ground) Assuming that all sounds correct... The outlet has a L14-20 receptacle, which is for a 4 wire plug. I assume this is for a range or dryer that uses 220v and 110v? Will this work, or do I need to replace the receptacle?

I'm installing a tankless water heater that requires one 60 amp breaker and #6 wire to serve it. I have installed breakers and new circuits in panels before but this panel is inset into the wall of the garage which presents an issue. Here's some info and my plan: - Run individual #6 conductors (& ground) in PVC conduit from the heater to the panel along the surface of the garage wall (about 12 feet). - The water heater has a 3-foot pigtail coming out of it with 2 #6 wires and one #8 ground. - I plan to have a junction box to connect my new #6 wires to this pigtail, then run the new wires in conduit the 12 feet over to the panel. - (for code purposes, I'm in Jacksonville, FL) - (panel is a Siemens with 150 amp service) - (I'm removing the old 30 amp breaker that served the old tank-style water heater) - (a local electrician told me that my panel could definitely handle the new 60 amp breaker provided I took the old 30 out of service) My question is, well.. first, does this sound ok so far, and then how do I route the three individual #6 wires the last 5 or 6 inches from the surface conduit run into the wall (through the drywall) so I can enter the panel though a knockout? I'm not sure there's enough room for a 90 degree sweep elbow to make that turn. Or can I just use a small 90 inside the wall from a junction box next to the panel (the box would provide a point for the surface conduit run to terminate). Thanks. Eric
