If I ever do build that 30 x 40 garage I will probably put in a 400
amp panel out there and sub feed the house. That 200 Amp service is
pretty busy.
### My electrician buddy said 240V 400A service was
available...and "no sweat". 400 A = 96 Kva ! 200A = 48 Kva.
I still don't get it. I have "200 A service".... and SO do my
15 neighbours... all hanging from the SAME 50 Kva pole pig ! Some
of my neigbours have a secondary suite in their homes... with a 2nd
elctric stove, etc.
### since we all got natural gas back in 1992... most of the
electric hot water tanks and oil furnaces have gone bye bye...
reducing the overall load..a bit. I still don't see any natural
gas clothes dryers..yet. Back East, they all have em... plus
gas ranges. My hot water tank, fireplace, and furnace all run on
natural gas.
### Bottom line is... when I smoke the pole pig at dinner time one
night..... I guess I can just whine to the pwr co... and say .."I'm
supposed to be getting 200A CCS service... so where is it? "
### The biggest pole mount pole pig I have seen is 100 KVA. But
these were special one off units...designed to drop 25 kv down to
12.5 kv..... then 12.5 kv into our vault xfmr at work... where the
vault xfmr dropped it again to 208/120. This is all 3 phase... and
both the 3 x old 75 kva xfmr's.. and the 3 x new 100 kva xfmr's
are huge... when u see em on the grnd. Every time I see 3 x
75/100 kva xfmr's.. all on the same pole, I cringe........ the
weight is massive.. as in 2 tons.
### anything above 100 KVA per phase... and it then goes
on the grnd.
Later... Jim VE7RF
