I finally got the new window installed in the front of the shop. I drove 1.5 hours to get a 48x36 window, and when I went to install it, I realized that someone had laid a 36x48 window on it's side in the spot where the 48x36 windows went.
So after another 3+ hour round trip I finally had the right window. I'll post pics of it tomorrow.
I think the next thing I want to do is deal with the electric. I've never hired an electrician before. Most stuff I do myself. When I finished out my walk up attic and added two bedrooms my father came over and helped with the electrical.
I decided to replace the (2) 230 volt outlets for the A/C units with regular dedicated 115 volt outlets. After researching A/C units I discovered that a 115-V Dual Inverter unit is actually more energy efficient than a 230 volt unit.
I also discovered that a 120 volt 140 Amp Lincoln Welder will handle what welding needs I have, so I don't need a 220 outlet for a welder either.
I feel like hiring an electrician to completely rewire the building would be expensive.
I feel confident enough to run all the wire and install new outlets and light fixtures using the circuit diagram suggestion posted here by
@ericbphoto. I even feel comfortable installing the circuits in the breaker panel.
Concerns:
NOTE: The electricity to the building is not turned on. There's power at the meter, but no power from the meter to the breaker panel.
This building was wired with a subpanel fed directly from its own meter, so there's no main breaker.
My concern is wiring the power to the panel from the meter.
I have wire coming in from the meter that has a Red wire, Black wire, and White wire. It seems like in examples I see there's (2) black wires and not a red wire. I realize that the black and red are hot, but I don't know if they're a proper gauge. I want to replace the old Federal Pacific subpanel with a 100 amp breaker panel. I don't want to have a 100 amp main cut off switch if the wire coming from the meter can only handle 60 amps. I'm also hoping that these wires going in to the subpanel are long enough to reach where they need to connect in the 100 amp panel.
The other problem is the ground. As mentioned and shown before, the grounding strap coming from the meter is broke just above the grounding rod. So the meter needs grounded, and I need to know how the new panel is grounded, or serves as a ground when it's wired with 12/3 wire that has a ground wire. Does a ground need to run from the new panel to an earth ground?
Also, the power from the meter comes through the block wall in to the bottom of the subpanel, and it's not in any type of conduit.
Options:
I've wondered if I should:
- Go broke and let an electrician wire everything
- Wire all the circuits and have an electrician make all the connections in a new panel and address the wiring from the meter and ground
- Wire all the circuits in to a new panel and just pay an electrician to make the connection from the meter to the new panel
- Go ahead and just wire everything in to the new panel including the wire from the meter providing it's a proper gauge for the 100 amp panel
It's possible that I may find that I need an electrician to replace the wire from the meter to the panel with a larger gauge for the 100 amp panel. Would it be possible to replace the 100 amp main breaker with a 60 amp main breaker if the wire coming in to the building is only rated for 60 amps?
Is it correct that 100 amp service should have at least #4 copper wire coming in?
