FranWhen two hot wires are connected, it creates a short circuit which can lead to excessive current flow, overheating, and potentially a fire hazard. It is important to never directly connect two hot wires together without proper safety precautions and electrical protections in place.
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.
If 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.
This 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.

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 does not matter which hot wire (red or black) is connected to L1 or L2 for a jet pump pressure switch in a 240V setup. The important thing is to ensure that each hot wire is connected to one of the two load terminals of the pressure switch. Make sure to also connect the ground wire for safety.
What side of the outlet do the red and black wires go on 220 outlet?
In a 220 volt outlet, the red and black wires are typically connected to the two hot terminals of the outlet. The white wire is connected to the neutral terminal and the green or bare wire is connected to the ground terminal. It's important to consult a professional electrician to ensure proper installation.
Why would a light switch have two black wires for power and two whites caped off?
Having two black wires connected to a light switch indicates that it is a switch loop, where one black wire brings power to the switch and the other black wire carries power to the connected light fixture. The two white wires capped off are neutral wires from the power source and the light fixture, which are typically not connected to the switch.
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?
The wire that is connected to the black screw terminal on the switch is the hot wire. This wire is carrying the electrical current to the switch. The white wires connected to each other are neutral wires that are not carrying current.
You touch two hot wires together breaker box will not turn back on did you burn the breaker out?
Touching two hot wires together can cause a short circuit, which may have damaged the breaker. It is important to not touch hot wires together as it can be dangerous and cause damage to the electrical system. If the breaker will not reset, it is recommended to call a licensed electrician to assess and repair the situation.
