I think we're using different terminology. I'm referring to main lugs as in breaker box terminology. Here's what I mean. It's a box without a dedicated main breaker. You can install breakers within it to act as a main, but it's not a true main box. This is the exact box I'm going to be installing in the shop to replace the existing box. It is a true main breaker box with a dedicated main.This is important. First there is no such thing as a "lug" ( connection device) "acting" like a breaker ( circuit interrupter)
Again, I'm no electrician, so I may be using improper electrician terms. I'm just using the correct product terminology.
It is about 8 inches above the 125A "main" box on the pole.Where exactly is the actual power meter?
To be crystal clear, I have 2 different professional licensed electricians arriving Monday for their input, and I'm not touching anything myself. I know my limitations, and beyond replacing a breaker, electricity is definitely one of them.An MLO panel IS a "sub panel" so what is the breaker size of what feeds this? ( it may be rated for 125 amps but that's not a certainty that its being FED 125 amps so it could be being starved on the front end)
I do presume this is 240 (220) VAC coming in at this MLO panel?
That MLO panel should be fed by probably #2 conductors and neutral (220/240) with a ground rod
Is there a fused disconnect?
At a minimum I would have #4 feeding the house and shop panels and break into 120 at those panels (I would put a main in each panel) This would be G&B all the way through.
Then rewire that death/fire trap starter/compressor.
Again, this is an indierct commentary based on an observation of your posts and actual decisions should be made by a licensed electrician under the authority having jurisdiction for your particular code.
To further clarify, using the above links as the basis of my terminology, the 125A "main" lug box has a 125A capacity, the 2-pole breakers within (which control the other subpanels/lugs) are 100A for the house, 60A for the shop, and an unknown 30A.
I'm assuming MLO means Main Lug Only. I have no idea what conductors/wires feed it. I'll have the electricians evaluate that.
A fused disconnect? No idea. Don't even know what that is.
Compressor starter will be corrected. So will the breaker box in the shop. You'll see why in the next post.
