Coming out of a 400a 3r disconnect into one end of a 3r gutter. We will need 8 nonmetered disconnects out of the gutter for 8 retail spaces. 2 disconnects will have 1-1/2" nipple between gutter and disconnect. 6 disconnects will have 1-1/4" nipple between gutter and disconnect. All conductors will be larger than#4. However, both prohibit more than 20% cross-section fill and have adjustment factors when more than 30 CCC are installed - 310.15(B)(3)(a). Dimensions of the gutter installed is not the determining factor of whether or not to derate - the number of CCC is. Custom fabricating a gutter should have had no bearing. I’m entering the gutter 14” from the bottom with 3” conduit. 2 sets of 4/0 will enter through that. One set will go up 23” and out the top. One set will go down roughly 10” and out the right. It’s a 6x6 gutter. Am I sizing it to 8 times the 3”, 6x3” or 8x2” or 6x2”. Exit knockouts are 2”.
So I have a service that hits a CT cabinet and meter, then penetrates the building and hits a gutter box. Inside this gutter box the hots are splices and they go off and hit 4 different disconnects which hit 4 separate panels. Inside this gutter box, the neutrals and grounds are all bonded together and bonded to the housing. This is incorrect?
Just wondering, what is the purpose of gutter boxes. I'm a new electrician, my foreman explained it to me, but i didn't understand. There's 4 emt pipes coming in through the concrete wall, then its going straight up. But i'm supposed to install a gutter box.
Back in the early 1980s as a apprentice we used what we called gutter nipples to connect motor starter enclosures and fused and non fused disconnects to wireway, trough or gutter. The so called gutter nipples had 3 pieces, a locknut, a somewhat long chase nipple and a spacer that fit between the gutter and the enclosure. Looking for some help trying to size a wireway (gutter) for a service. This is a residential 325amp service that will feed two separate meters (1) 200amp and (1) 100amp. I will be bringing a set of 350mcm into a wireway from overhead then tapping a set of 2/0's and #2's with some polaris connectors. Tapcon the box to the brick or throw a spacer behind it and screw into the sheathing behind the box. Install the light with the canopy that will cover it all. Profit. Sit down and eat your bacon sammie while watching the other guys .
Grounding Conductors to Boxes. Where circuit conductors are spliced within a box, or terminated on equipment within or supported by a box, any equipment grounding conductor(s) associated with those circuit conductors shall be connected within the box or to the box with devices suitable for the use in accordance with 250.148(A) through (E). As I'm getting solar system quotes, the electrician/owner (30 years experience) says he would need to mount a gutter box above the main panel to do the wire splices for select circuits that would be moved to the new subpanel next to the main panel, for the solar backup power circuits, since the wires might not be long enough to move sideways a couple feet.
