[RE-wrenches] Load Side Tap

[Max Balchowsky]

Fellow wrenches, I've got an install that is a little different than any I've done before. We are going to put an 18 Kw groundmount on the side of a hill (nothing new so far).
The Array will be about 150 feet from a 200 amp MLO subpanel in the garage of a guest house. Still nothing new. The sub panel is 500 ft from the 400 amp main service. The 200 amp sub feed is 250 MCM. There is not much load on the 200 amp sub panel. The twist on this one is this, there is a pull box in the vicinity of the proposed array location. It contains the feed from the House Main (250 MCM) It simply loops thru the box, I'm sure because of the length of the run. We are 400 feet from the main 400 amp panel and about 100 ft from the 200 amp sub panel. My thoughts are to tap the 250 MCM in the pull box to back feed the subfeed to the Main. The other option is to pull wire from the pull box to the sub panel and land a breaker for the 95 amp feed from the array. Any thoughts??
