They both are grounded; thus, they have safety features built into them. However, you should still use caution especially when you wire v. While most consumer goods, including portable electronics and most appliances, run on v power, some require v.
Appliances, such as dryers, certain oven ranges, heavy-duty power tools, and compressors explicitly require v power. A typical v wiring schematic requires three different wires: hot, neutral, and ground. With v wiring, both three and four-wire setups are possible.
The red and black wires in v setups each carry v, and the green wire is the ground. With four-wire setups, there is a white wire which is called the neutral or common wire. When the wiring is complete, the respective outlets for v and v power are different as well. Standard v outlets are made for three-pronged plugs, the middle of which is the ground. The other two are made in different sizes so there can only be one way to insert the plug.
With v outlets, there are either three or four holes per outlet. When wiring for v power in your home, you have to link the current in amps with the voltage of the particular wire to create the wattage necessary to power dryers, power tools, and so forth. You must install different breakers to provide the amps.
From there, gauge electrical wire runs from the breaker to the specific v outlet. At first, discussing the difference between v and v power can seem complicated, but remember that they are really two sides of the same coin. With the current level fixed in a home, the volts must be increased in order to provide that power, which is where v wiring provides the needed boost.
Also, v power is more efficient in terms of current because it requires less to provide the same power due to the increased voltage. As mentioned previously, however, this increase also means v poses a higher safety risk than v. For questions regarding v and v power, call Speedy Electric today!

That is because AC creates inductive effects - this is the reason transformers work. You are causing high EMFs, which in turn cause vibration, which causes fatigue and arcing failures, and eddy current heating in anything metallic anywhere near the imbalanced wires.
And the wires are running through all-metal conduit. That reduces the chances of fire, but wildly increases the eddy-current losses; you're essentially turning the conduit wiring system into a giant electromagnet. That could cause voltage drop at the appliance, which for a switching power supply will cause it to draw even more current. So all of your numbers could be wrong. And you are planning to run this circuit near limits. You're violating the "No cable should have two pointy ends" rule.
The reason for that rule is it's possible for one to be plugged in while the other is in your hand. So that means you can get nailed by it, since one prongy end plugged in will make the other prongy end hot. You can trip over a cord and pull it out and have it hit you. Or it can short against equipment, causing arc damage kind of a big deal in a rental and potentially starting a fire.
There is no practical way to make this thing fully de-energize until both plugs are plugged in. You're in a large commercial development. You don't have "V" actually V. You have "V" actually V 3-phase. When you figure the additional losses from turning your building into a giant electromagnet, say your practical voltage is V.
Now take your "W" load. I kinda doubt it. VA is the number we have to worry about with breakers and provisioning power. So your VA into useful volts - you are now at Even if we assume ideal V, you're at The thing about this building is, it's a commercial building. It's wired in metal conduit. That means a competent electrician can fish a couple of blue wires through the existing pipe, and hook you up with a V dedicated circuit that's all yours.
It can be a 20A circuit if your device is able to work on that given the above provisos , or a 25A or 30A circuit if the numbers show that it needs that. So the right answer here is to ask management for the service you need. It's not far out of their way. That will comply with certain Code requirements that require V receptacles at a certain spacing. Do not do this with your idea to make or get some type of Y-adapter. It is just too crazy dangerous to do this. In addition the fact that you have to ask this question here to learn about it is a demonstration that this is not a good idea.
There are many factors that have to be considered and even in a few comments under your question not all of those factors will come out in discussion.
This will leave you thinking that you fully understand the issue when in fact you would not. I know you claim that you have control over things and that you would subscribe to the safest handling of a kludged up connection system Do not do this. Hire an electrician to do this properly. I know you said you have to wire this yourself but I suspect that you say that because you may not even have legitimate grounds to even consider changing the wiring.
The community nature of your building with power panel behind a locked door seems to indicate that you do not have the free right to go changing things like this. Sorry to have to sound so harsh about this but crazy ideas like this have to be stopped before they get out of hand and someone gets hurt, killed or serious property damage occurs. I have done this before, and it worked perfectly. All of the other offered advice in the comments are valid, as this can be dangerous if someone besides you will be around that could be handling your cabling.
As mentioned previously, you would have to source your current from two different outlets that are out of phase with each other, and the total current available will be that of the lowest value breaker on the two circuits, in addition to any other load on any one of the two circuit breakers.

Asked 2 years, 2 months ago. Active 5 months ago. Viewed 10k times. Good morning electrical geniuses, here's a problem for you. I'm not an electrical engineer, I'm a mechanical one Improve this question.
Evan Ledwith. Evan Ledwith Evan Ledwith 21 1 1 silver badge 6 6 bronze badges. There is no current in the neutral so you don't get 40 A, you still get 20 A. Do it properly. Thank you for a quick answer. I understand the dangers behind that, however, this is a 1 room apartment effectively and I am the only occupant.
I have the ability to secure the plugs to the wall. I understand now that the Y setup would give me 20a, however, would it be possible to do 2 Y adaptors on 3 different breakers, and use those 2 separate v 20a circuits?
I realize this would double the strain on one of the outlets, but would it be dangerous? It shoudl evenly split at 15a per circuit? JRE -- and replace the two breakers with a single two-phase breaker or add a mechanical link between the two breaker handles.
I have down voted this question to alert to the fact that this should not even be considered.
