Here...
You are supplying a separate structure. There is no rule that says one service can only supply one structure.
Some will say you must have a disconnect for the second structure grouped with the one for the first... but in truth, that is not required.

Im with Electricalist im learning. i get the best advise from this forum. even reading previous post and answers helps when I get into trouble, just like the bible. lol
BTW. Part of same question as above we wanna install a H frame in anticipation of T buildings being delivered ,per the customer request . don't ask why that's what they want. : - (
Anyway. would the H frame be considered a separate structure and the T building be another? would i have to build a new service ON t building?
thanks
With 20' of air in between, most will say yes.
Cut that gap down to 6', and I guess it'd be around 50-50 to 25-75.
You wouldn't necessarily have to build a new 'service', but disconnecting means will be required... and you are only permitted to have one service/feeder with up to six grouped disconnects without special permission otherwise.
thanks! let me pick ur brain one last time.
what if I installed 1-600a disconnect at first service H frame then ran to a gutter at 2nd H frame with the 3 grouped disconnects. Each disconnect supplies 3 different panels for T building. you think that falls under 225.30
Yep. That's a violation I've never seen or heard interpreted otherwise. You're only permitted one service or feeder to the T building.
Are the T building panels grouped? Outside or inside on outer wall? MCB or MLO?
No Sir
T building panels not grouped they set about 50' away from each in the Building on inside on outer wall with MCB. what about the 600a disconnect at the 2nd
H frame feeding all three panels from the 600a disconnect. No separate 200 amp.
sorry last question.
You'd have to put a disconnect(s) on (*or inside nearest the point of entrance) the T building any way you look at it. Running overhead, I'd just eliminate H2 all together, put a 600A at H1 (only because T building is temporary), and put 3?200A fused disconnects on* T building to feed panels.
Hmmm... a temporary building that requires (3) 200A panels. That sounds like something a utility would do... and the building's still there 30 years later... :slaphead:
like I mentioned earilier in thread We thought the buildings were gonna be separate buildings. These will be all together. The buildings will set in a parking lot for now. To save money they wanted to use a 800a existing service not being used and will end up being demo once project is over. them grouping the buildings together ruined my plan to run three separate feeders one for each t building. no tomorrow I have to figure out how to get this done.
With your help I have a good idea how to approach the situation. THANK YOU!
Is there any existing service disconnect? Fused?
yes they have 4- 200a service disconnects that were feeding existing equipment that is now gone. I was planning on using this before the grouping of buildings.
Had a thought... but amounted to a violation... and thus deleted it...
