I have cabin near our primary residence that has electrical service. :
Here you see the meter head and a 'sub panel on the pole outside of cabin. the breaker in this panel is 200a
A close up shows two conductors and a neutral out one knockout and two conductors (but no neutral) out another knockout(right side)
On the indoor main panel of the cabin, things appear ok, two conductors and a neutral on 100a main breaker:
Now, out in the barn, which is approx 100f from the pole with meter head and 'sub panel' (first pic) things aren;t so great:
This is a 100a main with two conductors and a neutral, though the quality of workmanship and materials leaves much to be desired. The two conductors do indeed originate from the 'sub panel' under meter head on pole near cabin. The two conductors are trenched and run through pvc conduit:
Note the two conductors in conduit, and the #4 on the left is the neutral in the panel in pic above. The problem, this neutral does not originate from the 'sub panel' below the meter head, nor does it originate from the main panel inside the cabin! I really don't know where the neutral is coming from, but perhaps it's tied to a ground rod somewhere.?.
My questions are:
-Are the two #4 conductors ran in conduit from 'sub panel' on pole sufficient for the new 100a panel I plan on puttting in the barn.
- Should I pull a new #4 neutral (or smaller?) from sub panel on pole to my new box in the barn?
- Should I put a ground rod at barn and ground panel in the barn?
I am having trouble w/ power in barn. if I run a good inductive load (my good circular saw), the saw is slow to start, never reaches max speed and is easy to stall out. compressor seems to run fine though on 220 in barn.
