Power comes off this main panel to a sub-panel in the out building. We also have a separate 750 sq' building in our back yard. I know this house went through all the proper inspections. We had it built so we are the only occupants. There are other pictures of how the box looks on our outside wall, the panel labels, the bottom of the box, the model of breaker box, etc.
The wires you think may be too small do not have any printing that I could find. The other shows me holding a ruler up to the wires and maybe you can tell what gauge the wires are from that. I can see "AWG" and then the number was partially worn away. One of them (rotated 180 degrees to make it easier to read) shows the printing on the large wire that connects to the 30 amp breakers. GREEN WIRES NEVER should carry current, only in a fault. White wires MAY be used to carry current just mark them with black tape. Mark the white wire with black tape to induicate the wire is being used as hot.
If the outlet is a 220V "only" then you only need to use 2 wires and a ground, like 12-2. AS long as this warning is heeded, there is no problem, but one must be careful when you have a panel such as that one and one moves breakers and wires around on breakers within the panel. If this warning is NOT heeded and both the red wire and black wire are on the same single space dual breaker(or the same phase at all) the nuetral can heat up with 2 times the current and cause a fire EASILY. The problem is this, with a shared nuetral circuit it is IMPERATIVE I repeat IMPERATIVE that the balck and red wires associated with a common nuetral are on different phases in the panel. This is "OK" but a potential for problems (could be big problems) if not treated the right way especially that you have so many single space dual breakers and shared nuetral circuits. You also have MANY "shared nuetral" circuits, hence all the red wires and the lack of the same amount of white nuetrals. You have MANY dual single space breakers which "technically" should not be in that panel. What you have here is a "main lug only" panel which has been boogered up to be a main panel. Does it matter which side the red and black wires are attached?
* I know the bare ground wire gets attached to the green screw on the outlet. Only the red, black and ground wires are hooked up. In other words, the white wire dead-ends. * My other 220 volt outlets have 12/3 wire with the white wire attached inside the breaker box and then capped off inside the outlet. * Back in the garage, mount the outlet box, attach the 12/3 wire to the 220 female outlet, mount the outlet, turn the power back on and test with a multimeter. * Attach the red wire to one of the breakers, the black wire to the other, the bare ground wire to where the other ground wires are attached, and the white wire to the bar with all the other white wires. * Mount a double pole 20 amp breaker (two 20 amp breakers in tandem) in the two available adjacent slots under the 30 amp double breakers. * Fish some 12/3 wire up inside the breaker box. * CAREFULLY cut a hole in the dry wall about one foot under the breaker box panel for the 220 volt outlet box. Looking at how our other 220 volt 20 amp outlets are wired, here's my plan: Before I attempt this myself, I thought I would run my plan by the forum users who have much more experience in this type of job. I was thinking it should be fairly simple to add a 220 volt outlet right underneath the breaker box panel inside the garage. Behind the garage wall drywall, on the outside of my house, is my breaker box panel. I do not have a 220 volt outlet in my garage.
#220 VOLT PLUG PORTABLE#
Here's the situation: I recently bought a portable 220 volt compressor that is rated at 15 amps. I have done some simple homeowner type of 110 volt wiring, but I've never worked with 220 before.
