hook up delta wye transformer
Once the door and plate are removed you need to remove two knockout tabs for the double height volt breaker. Between the handles are crimpers for a variety of wire terminals and a very powerful wire cutter that can cut Romex cable in a single shot. With the main breaker off, the buss bars that the branch circuit breakers connect to hook up 480 volt transformer isolated from the incoming voltage and will be hook up delta wye transformer to work on. If you have V across them, the breaker is straddling both busses. The hot wire for a circuit is connected to the breaker by a set screw on the base. Not that breakers don't sometimes fail, but more often than not, the breaker is just doing what it's supposed to do, and the problem causing the breaker to trip needs to be rectified first. Use a flashlight as necessary to see. Insert the gauge, 4-conductor cable through the cable clamp. Take note that even after taking off the panel cover, you don't ap access to the main breaker breake without removing the main compartment cover as well. As I got more and more questions, it's expanded to the montrosity you see today. Also look for broken light sockets or other damage that may be causing the device to short when plugged in. In the sample picture hook up 480 volt transformer the ground strap in folded over and is connected to the center connector but NO connection from it or jump to ground. Continue to 3 of 10 below.
I inherited a main panel box from a homeowner that wasn't always fond of meeting the required NEC codes. As such, there are some oddities in the panel. Specifically, there are two Murray MH-T amp breakers. These are tandem breakers and not "slimline" or "thin" breakers -- the two breaker switches on each are not connected in any way.
One of these breakers is used for the clothes dryer and the other for an electric water heater. The neutral is connected to the neutral bar. I want to stress that this absolutely is working. Both the dryer and water heater were wired this way well before I moved in and it's only now, years later, that I noticed what was going on. It's worked fine all along. This seems all sorts of wrong, though.
It's still a single pole breaker, even if hook up delta wye transformer are two v circuits coming off it. It seems like if this was okay, that I'd hear about using a tandem hook up 480 volt transformer as a space-saving slim v breaker So, what's wrong with doing this? What's the ramifications if I don't change these two out with traditional double-pole breakers? Added photo of the breakers in question: The very top is a double-pole amp breaker that's fine.
The first amp tandem is the dryer breaker and the second is the water heater. Added photo of the dryer breaker popped off the panel: You can clearly see the two buses and that there doesn't appear to be any shenanigans connecting the two of them. I removed the top double-pole breaker for clarity. The popped dryer breaker is clearly a single pole, as hook up delta wye transformer can see the one entry slot.
Hook up delta wye transformer apparently connected to the left bus and only that bus. It sounds like you may be mistaken as to how this is wired, or that perhaps I'm just not understanding your explanation. Each tandem breaker provides 2 V circuits, this is true. However, if you measure between the terminals on a single tandem breaker, you'll get 0 volts.
This is because the terminals are both powered from the same leg, and so are at the same voltage potential. If you measure from a terminal on the top tandem breaker to a terminal on the bottom one, then you'll measure volts. This is because each breaker is connected to a different leg, which are each one half of a volt circuit.
With all that said. For this setup to work, one appliance would have to be connected to both breaker. Notice that each appliance circuit has one wire connected 30 amp breaker hook up each of the tandem breakers. In this situation, you'd need a device like Speedy Petey shows. Notice how the inner handles are tied together, and that the outer handles are also tied to each other.
This way if either trip or are turned off by the userthe entire circuit is shut hook up 480 volt transformer. If this is wired the way you've explained, where the dryer is connected to the top tandem and the heater is connected to the bottom. Then there's some magic going on in those breakers. What you have will electrically work fine, but it is not code and not safe for anyone working on these units. In US household electrical service, you CAN'T get V from a single pole. If you have V across them, the breaker is straddling both busses.
You just can't get v from the one bus. The only issue is connecting the two switch handles. Obviously a nail or piece of wire will work but it looks shoddy. There actually is a real product for this, called a circuit breaker handle tie. I just bought some myself at the local big orange home improvement store to replace a piece of wire stuck through one of mine.
Modified to match to new provided information. Speedy Petey's answer contains the circuit breaker you need to install to correct the situation. As you can see from the breaker inter-ties, they basically take two of these breakers and manually finish off what the installer was attempting to do in a safe manner. Murray MH-T MP this unit gets its power from one leg to produce two V circuits. The setup is working because each breaker pair feeds off the proper panel bus leg One attaches to L1, the other to Mate 1 dating site. From your added information, each V circuit is split across the hook up 4 way light switch breakers to do this.
What's Wrong -- The major safety concern here is that with a circuit fault, only one of the breakers in the set may trip, leaving the V circuit partially energized. For instance if the dryer heating coil burns through and one end touches ground, that side will trip, leaving the other 30 amp breaker hook up hot. You definitely want a circuit fault to totally power down both legs.
Also related is the fact that anyone not paying attention to the panel setup may power off the circuit to work on it and not realize they switched off adjacent pairs instead of alternate pairs of each V circuit, leaving a hot leg in the circuit they think is powered wye transformer hook up. You want things to be fail-safe. This isn't fail-safe, but is a booby trap waiting for the inattentive or hurried.
NEC frowns heavily on things like this. Murray bus backplane with interleaved fingers so adjacent full size breakers are on opposite legs. Not true for the MH-T MP breaker pair, each breaker in the set is half-width and the combination is fed off only one leg blade. I have read that tandem breakers can be mounted to either feed power from one leg of the bus bar or from two different legs. If it's the latter in your case, then you'd be getting V after all.
Check the terminals of the breakers in question or check at the outlets where your appliances are plugged in with a voltmeter, if you haven't already, and confirm what is actually being fed to your appliances. I ran hook up delta wye transformer a panel today that has a water heater and a dryer hooked up using tandem breakers. They are not split either. This panel is configurable to half a slot, meaning a regular VAC breaker would be clipped into 2 prongs of a live bus, and there is a small plastic wall separating hook up 480 volt transformer B side from the A side keeping you from shorting the two VAC circuits together.

Let the experts guide you through yout dryer circuit wiring and hookup project. The red and black wires from dryer cable connect to the dual 30 amp breaker. The first 30 - amp tandem is the dryer breaker and the second is the water If you hook up a v appliance to a double-stuf, it won't work. the steps involved in installing a new volt 30 amp circuit and breaker. Next, connect the two black hot leads to the circuit breaker. Connect the black and white wires to the breaker and the ground wire . The 30 - amp circuit breaker you installed won't pop and the wire.
