[RE-wrenches] Sol-Ark 15k

Mon May 9 23:06:40 EDT 2022

Sure, We are putting together a system w/ (8) Sol-Arks, (2) 400A transfer
Switches and (4) 400A load centers sitting on 10 x 10 gutters, No nipples
or raceways between them, we just cut a large portion of the bottoms or
tops out the enclosures with matching windows cut out of the gutters.
Nipples (Chase, Short, conduit and offset) are only used when absolutely
necessary. I will also use 2.5 x 2.5 wireways vertically in lieu of flex or
raceways. Internal and external elbows too. I've always designed electrical
rooms with the idea that the equipment will be swapped out in a decade or
two.  Also using a 20' long 10 x 10 gutter with 3/8 x 4" bussbars and 2.5 x
2.5" to connect 24 Discover AES's on this one. We'll have some pictures in
a month.
