    How do I identify multi-wired circuits?

    I wonder if I could get a new blank panel label? I'll need one.

    How do I identify multi-wired circuits?

    Thanks for checking on my panel. I had a suspicion that they were on the same buss...and confirmed by tracing and taking meter readings. Also the lower left section of my panel is unused...so with the cover off and can see how the physical buss/breaker attachment points work.

    How do I identify multi-wired circuits?

    What would I confirm? I confirmed by clearly tracing each individual red wire up to the individual cable that contained its white, black, red, and ground wires. Then I carefully traced the black back down to its breaker/circuit. Each set of MWBC were: 1) black wire/circuit directly above the...

    How do I identify multi-wired circuits?

    They look to me as #14. Go back to page 1 and see actual photos....

    How do I identify multi-wired circuits?

    I checked a couple of ways.... 1) I installed an extension cord into the frig outlet, and took a reading with the outlet that I thought might share the neutral (which it does based on the tracing that I did later), making sure I went into the hot inputs.....got zero volts. 2) traced the wires to...

    How do I identify multi-wired circuits?

    The last column shows the circuits that share a neutral along with color denoting which phase. I enhanced on colors on this attachment.

    How do I identify multi-wired circuits?

    yes......and did that for each MWBC. Each one is in a position of A/B. To get 240V (different phase) each one needs to be in position B/A. Also, the bottom of my panel on the left side has some empty spaces...and I can physically see how it works in order to get from one leg to the other leg...

    How do I identify multi-wired circuits?

    Ok...first of all, the idea of using a generator is not the subject for now...so forget that. What I wanted to know was what circuits share a neutral. I was fairly sure that I knew just from seeing what circuits were near the red wires, but I was not certain. So, I traced every one of...

    How do I identify multi-wired circuits?

    So I thought I would give a follow-up as to what I found...plus I have a few questions depending upon what I might do. I first validated what each circuit actually powered, top to bottom of the right side of the panel. Actually found a few labeling mistakes which were all within the MWBC's...

    How do I identify multi-wired circuits?

    No one is saying that you run a toaster and microwave at the same time with a small generator. In fact, I would simply turn off the inside frig for whatever time we would need to heat food in the microwave. The microwave is 1,700 watts max. I've done this many times before over the last 20...

    How do I identify multi-wired circuits?

    Sparky I appreciate your input....so for now lets put this to rest until I can do some tracing.

    How do I identify multi-wired circuits?

    I'm beginning to wonder if all of my MWBC's are already on the same phase. I say this because wire/breaker #13 (black) and wire/breaker #14 (red) look to be smaller gauge (maybe 14 gauge) whereas the wires above them look to be 12 gauge. You're not going to get a cable with two different size...

    How do I identify multi-wired circuits?

    So if you look at one of my photos, the first breaker (top) on the right side is a 120v feeding the washing machine. The next two down is 240v service for the dryer. Counting the individual wires down the first red wire for 120v is wire number eight...just below the breaker that has a white...

    Running a house panel on 110volt only

    My new generator is a 4250/3500 120v inverter. Going with a bigger 120/240v inverter would have been impracticable. My old generator that I still have is a standard generator rated for 4000/3250. It never had a bit of trouble running both refigrators, fans, tv, small microwave, and some...

    How do I identify multi-wired circuits?

    If that was the situation, then I would have a potential problem now....generator usage or not. Correct? I think every other breaker uses a different leg.

    Running a house panel on 110volt only

    I guess you don't understand. My power outages are fairly infrequent and usually no longer than a few days. If I wanted to run anything 240v it would be my A/C, and for that I would need a significant sized generator and lots of gas...which is a PITA to store and not always availalble after a...

    How do I identify multi-wired circuits?

    This is a sub-panel in the garage. My house is fairly big...so the disconnect main panel is on the other side of the house (outside) with the main disconnect. It also has circuits, including running the pool pump/equipment, but no red wires for any of the 120v circuits. I clearly see that the...

    How do I identify multi-wired circuits?

    I guess that part of my issue....I hate messing with something so neat. Not trying to make simple into difficult, but the issue of mwbc is new to me so I want to be sure I don't do anything stupid when using a generator and creating a single phase into the house. Thanks for the help...

    Thanks Ipgenie....I have the answer I need....appreciate the input on using only 120v.
