Subpanel

I'm installing a subpanel to supply electric to a dryer and a water pump - both need 220. My electrician ran #6 wire from the service and I'm connecting it to the subpanel. I need a 30 amp breaker for the dryer and a 20 amp breaker for the water pump (it draws 12.6 amps). The electrician can't get back before the water well goes in. What do I look for for the subpanel? Does the new panel need to be grounded? Thanks!

 

The dryer breaker needs to be 240-volt, but you'll need to tell us whether the pump is 240 or 120.

The answers to your other questions depend on whether the subpanel is in the same or differnt building than the main panel.

 

The pump is 240 and the panel is in the same building. It's an attached, heated garage.

 

Below isn't all you need to know, but it's an overview. I can't cover all details because I can't see exactly what you're working with.

No ground rods necessary. Connect up the four feeder wires (hot, hot, neutral, ground) to the proper places, torquing the screws incredibly tightly. Secure the clamp at the box entrance, and secure the cable outside the box (if not conduit). Throw away the green bonding screw in the box (do not connect the neutral bar to the case). Install a separate grounding bar if not already in the subpanel. Insert the proper brand and model of double pole breakers and connect black, red, white and grounds from properly-sized branch cables (10/3 for the dryer -- probably 12/2 for the pump), again torquing very tightly. The pump breaker may need to be GFCI.
