    Pentair VS3050 Wiring

    Ok, dumb question...again... Wiring the Pump (220vac) to the ET panel GFCI. 1 hot to LN1, 1 hot LN2, where does the neutral go? Do I need a seperate Green (ground) wire from the panel to the pump?

    You don't use a neutral with 240 volt power unless you are wiring a sub-panel.

    Yes, you need a ground to the pump. I'm not sure what you mean by "seperate".

    The 220 GFCI breaker has connection for Load/Neutral/Load?

    The neutral wire on the breaker goes to the neutral bar in the panel.

    240 volt GCFI breakers come in two variants. Both kinds have two load connections and a white wire (usually coiled) coming out. The two load connections get wired to L1 and L2 on the pump, while the coiled white wire gets connected to neutral inside the panel. Some of them also have a third connection for load neutral. If yours has the load neutral connection you simply leave it unwired. In either case it is crucial that the coiled white wire coming out of the breaker get wired to the neutral bar inside the panel. In either case you also run a green ground wire from the panel ground bar to the pump. Sometimes the ground bar and neutral bar inside the panel are combined into one bar.

    It should be noted that on a sub-panel, the ground and neutral should NOT be tied together, as this would be in violation of the NEC code. Any sub-panel should have a separate neutral bar that is not bonded to the ground bar. In addition, if the sub-panel is attached to a separate structure (like a pool house or cabana), then a nearby ground rod must be installed and connected to the grounding terminal, along with a green wire run from the main panel. This is to minimize potential differences between the equipment ground at the main panel and the sub-panel.
