Hi,
You said you bought a cutler hammer spa panel. I went to Home Depot and bought one too. Can you help me with the neutral panel. There is a screw that comes with the box. It's for bonding the case to neutral. Should I bond the case to neutral or ground? Thanks to you or anyone that will take the time to help me out.

Don't use the screw to bond the netural to the panel. Inside the sub panel the ground and the netural are kept seperate. The panel should already be grounded by hooking up the ground wire to the ground strip.

Thank you for the help, ski. I may have another question as I go along.
