I need to replace a post-mounted load center that's out in an open field. The load center is a subpanel downstream of a subpanel from a guest cottage. The load center in the field was originally used to feed two separate post-mounted GFCI outlets (in weatherproof enclosures) that were used to power drainage sump pumps (that area of the property is prone to flooding in the rainy season). Now, in addition to the sump pump GFCI's, I will be adding two additional branch circuits for a well pump and a booster pump (for property irrigation). Obviously, the panel will be L&L for outdoor use.
The way I look at it, this is like a subpanel at a detached building (except there's no building). Is that the correct way to interpret this? There are 4-wire feeders from the guest cottage subpanel to the location of the new load center. So my intention was to:
1. NOT bond the neutral to ground.
2. Install a GES (GEC and ground rod) tied to the panel equipment grounding bar (to which the ECG feeder from the cottage subpanel is also terminated).
Does this sound right?
There will be four branch circuits: two 220VAC/20A circuits for the well pump and the booster pump; and two 120VAC/20A circuits to the two GFCI's. This is less than six main disconnecting means, but do I still need a main breaker as a service disconnect?
