Wiring to the circuit breakers is 220 volts. The circuit breaker box has 2 110 Volt lines. If you connect two black lines together from one side nothing happens. If the these two black wires are from different circuit breakers you may have a safety issue by back feeding the electricity.
If you connect 2 different 110 volt lines you will end up with a short. This ends up as a 220 volt short.

∙ 14y agoIf it is a white wire with just a black end, the black is tape. This is done to show that it is a return hot wire to a fixture or switch. Smaller wires in appliances can use many different combinations of color.

∙ 14y agoIf you are talking about the two wires when looking in a switch junction box or light junction box they will be the switched leg. The white wire is supposed to be identified with black tape to show that it is a current carrying wire but in a lot of cases this does not get done.

∙ 14y agoThis sounds like a typical light switch connection that turns on an overhead light fixture. There are two pairs of wires in from the supply voltage and two pairs of wires out to the light fixture. The two white wires are connected together in the back of the box. These are the neutrals from the supply to the light fixture. The two black wires are the ones that get attached to the switch. Incoming "hot" to the top terminal of the switch and the outgoing black to the bottom terminal of the switch. If you just touch the two wires together as you explain in your question then the light fixture should come on.

∙ 14y agoDepending on how the two wires are connected in the circuit ,one scenario is the breaker to that circuit will trip.

∙ 7y agoIt depends on the situation and what the black and white wires connect to.

When connecting a 240V line with two hot wires and a ground does it make a difference if the red or black hot wires are connected to L1 or L2 for a jet pump pressure switch?
No, it makes no difference. The selection of red and black "hot" wires on your 220 line is arbitrary.
I have Two black wires and one red wire conected to a switch. Which is hot and which is neutral?
It sounds like your switch is a three way switch. The wire that is on the different colour screw of the three screws will either be the "hot" wire or the wire to the load. The neutral might or might not be in the box that the switch is in depending on which end of the three way system you are at. See discuss question button below.No wires connected to a switch are neutral. A switch breaks the circuit of the hot wire. Black AND red are hot wires. White is used for neutral and is almost never connected to a switch.
Can you connect Two wires to one main lug in a panel board?
Two wires can be connected to one main lug in a panel board if the lug is designed to hold two wires. The data will be written on the lug.
You touch two hot wires together breaker box will not turn back on did you burn the breaker out?
You might want to call an electrician... nothing usually happens when you touch two hots together.
How do you determine which wire is hot at a switch that has the white wires connected to each other and two black wires from different romex going to the switch?
Answer for USA, Canada and countries running a 60 Hz power supply service.The white wires are the neutral wires. One of the black wires is the "feed" hot wire coming from the circuit's breaker on the incoming power panel.The other black wire is the "switched" hot wire going to the load. (The light or whatever appliance the switch is controlling.)If you don't know how to tell which black wire is which, the hot is usually the wire connected to the top screw on the switch. In Canada, there is a rule that all hot wires are to be connected to the top of switching devices.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

Why there must be two wires connected to an ammeter?
Two.
Where are the hot wires on a Geo Metro ignition?
im assuming your looking for hot wires on the coil. They should be two wires of the coil
True or false-computers are connected with a network of wires on the internet?
Most are connected by wires, some are connected by a wireless connector ('Dongle'). Two of my friends have wireless dongles.

Which wire goes where on 220v socket?
If there are three attachment points then you have a ground and two hots. The ground goes to the green screw and the hot wires can be connected to either hot screw. If there are four wires then the hots will likely be red and black. The white wire is the common or neutral and the green or bare wire is ground.
Can you connect Two wires to one main lug in a panel board?

What is meant by 220 volts AC?
In US household electrical service there are two "hot" 110 volt wires and one ground. Only one hot wire is connected to a normal outlet or light fixture. To wire a 220 volt alternating current outlet, both hot wires are connected to the outlet. This is used for appliances that need more power than is provided by 110 volts like electric ranges, clothes dryers, air conditioners.
You touch two hot wires together breaker box will not turn back on did you burn the breaker out?
You might want to call an electrician... nothing usually happens when you touch two hots together.
How to wire a split capacitor motor?
Your two hot wires go to the load side of your contractor and the two brown wires go to your capacitor
What happens when you connect a 110 volt motor to 220 volts?
On a three wire supply system if you connect the two 110V wires together and they are across the phase they will short out and trip the breaker. If the two 110V wires are supplied from across the phase and connected to a motor then the motor will run. If the 110V wires are on the same phase nothing will happen.
