who want to pull apart my plan here? Ill try to do this without a diagram in the order from the pole to the house:
service single meter on my pole i dont need 400amp or 2 200 amp panels but that's just how it is. lots of room.
400 amp suitable for service entrance manual transfer switch.
-transfer switch is 2 pole, it does not switch neutral
-neutral bus in transfer switch is not bonded. i left the non bonded plastic screw in the bus bar and did not put the service disconnect sticker on the switch as per the instructions on the switch. if you bond it with the metal screw it said to put the disconnect sticker on. i dont want it to be considered disconnect as the 2 panels downstream are wired as individual mains with service grounds and neutral bond.
-transfer switch case equipment bond is grounded to a rod for the heck of it but remember neutral bus is not bonded to case
-50 amp twist lock receptacle wired to transfer switch AUX lugs
-service is spit in the transfer switch which has the lugs to do this it goes underground to 2 main panels from here, 3 wires to each.
#1-200 amp panel
neutral is bonded here grounds and neutrals mixed
system grounding rod
#2-200 amp panel
neutral is bonded here grounds and neutrals mixed
system grounding rod
split service with two main panels, each with individually bonded grounds/neutrals off one service is done all the time. i know this is ok
im not super interested in interpretations of the SUSE switch being my first point of disconnect, neutral is not bonded there so im calling it just a switch. my disconnects are my 2 mains, one on each panel. as long as this is safe, which the lineman that hooked it all up said it is.
generator plan
genmax 9000 portable inverter generator, parallel capable if i ever get another.
unbond neutral from genmax frame ground as it is bonded on both panels. if i ever use the generator stand alone, i will put a neutral to ground jumper plug in.
use 50 amp plug on genmax to 50 amp receptacle on transfer switch.
ground genmax frame to a rod
cooling fan in the generator enclosure plugged into 110 generator outlet. like an attic gable fan. i want it to come on any time the generator is running even if i haven't transferred power. but ive unbounded neutral on these outlets, so should i run it off a power strip with its own protection? it is a concern?
my only concern is safely hooking up the generator. All im coming up with in my head is that there is no system ground from the panels back to the generator. but the generator will have a grounding rod and has its own main breaker. the generators neutral bond will be through the cord to the panel bonds. so the house over current protection is as it always is when on line power. the generators over current protection is its 50 amp main and ground. am i missing anything? just tryingn to talk safety.
