I have a spa serviced by a 240v 4 wire subpanel with GFI breaker. I would like to add a 120v branch with a GFI outlet for light duty (light, music etc.)
Can I pull the power from one leg? I realize that I will have to ground the new line and use the one leg of 240v and white neutral.
Since it would have the existing GFI 240v beaker, how would I setup the new 120v GFI breaker?
The spa is 40' away from main panel, I would like to avoid burying another line and conduit.
Any ideas or concerns?
