It depends on the type of panel. Hook the breaker to the hooks that run along the out side of the bus area, then If it's a stab lock panel just snap the breaker down into place. If it's a bolt on panel once you have pushed the breaker down into place you'll need to start and tighten the screws that connect it to the bus, at your experience level DO NOT try to connect the breaker with the power on. Once the breaker is in place connect one of the hot wires to each of the breakers lugs. If you have a Neutral (white) connect it to the Neutal bus first. If this is a sub panel with a separate ground bus you'll need to connect the gound there.
If your hooking up a motor and it runs backwards just reverse two of the hot leads.

    i have 3 wires 2 goto the the 2pole breaker and 1 is grond right can u hook up the 2 wires to the breaker and they be backwards for a welder

    For a welder it won't matter. If you have a ground and a neutral bar the will not be insulated from the box, that's the one you should hook your ground to. If you hook it to the neutral it will work but there's a good chance of getting shocks from the welders case.

From the panel box to my electric furnaces breakers do i run two 110v wires one to each or do I run a 220v to each breaker that is inside the furance

More information is needed. What does the manual say you need? With out the necessary details needed to help I would assume it is 220V. Run a 4 conductor cable. It would have two phases (115 to neutral each) a neutral wire, and a earth wire which is connected to the cabinet. If this is confusing you best get an electrician to do it for you. If you mess up you could cause your facility to go up in smoke.

I have a 440v 50 amp and a 220v 30amp main breaker box outside my house. the 440 goez to the inside of the house and i have to unplug the 440 and plug in myown 440 plug i connected to another breaker box...

Some of these numbers don't make sense?
I have Never heard of 440v and 220v in a residential application, they are two different systems, 480 volt is typically 3 phase power, and 240v is typically single phase, more in likely you have a 200- 400 amp main service, and a 100- 200 amp secondary service for the welder, that can't be 110 @ 200 amps?
I would need more info, and pictures of actual nameplates of the equipment,
and then I could advise a safe NEC electrical code answer...

Wire schematic

If the welder is single phase 110v use a dedicated 20A standard household circuit. If 220v single phase use a 50A RV or weld receptacle connected to a 50A dual breaker with common trip. Make sure the breaker is the same brand as your panel. If the welder is 3-phase connect the wires B-O-Y (Brown Orange Yellow) at the breaker (3 phase 50A) and see if a color code match can be applied at the welder, although the only issue is whether the wire feed will run forward or reversed. If the wire feed is reversed then move any two wires of the B-O-Y set to change the rotation.

110v working 220v

Okay here goes, voltage does not matter as long as the breaker has the correct current draw (amps) for your load. Also 220 vac is normally provided by running two different phase hot lines into a double breaker. The difference in phase is require to make the item work properly. If you run two lines of the same phase into a double breaker then you still wind up with 115 vac. You might want to have an electrician do this if you do not know what you are doing. Not doing this properly can cause fire and/or lose of life and property.

How to conect three phase 5 wire conection to 4 wire 380volt three phase from the machine

Identify each of the 5 wires with voltage testing.
Find which breaker serves the 3-wire, and which breaker serves the 2-wire.
--You might have a 3-pole 3-phase breaker (with 3 hot wires) plus a single-pole breaker (with 1 hot and 1 neutral) ... giving a line with 4 hot wires and 1 neutral.
--Or you might have a 3-pole 3-phase breaker (with 3 hot wires) plus double-pole breaker (with 2 Hots) ... giving a line with 5 hot wires and no neutral.
The 4 wires from machine are probably 3 Hots and a neutral, or 3 Hots and a ground.

You need to identify where the ground wire is. One of the 5 wires from breaker box might be a ground.

I am going to install a 3 phase 100 amp circuit breaker panel board to provide service to 9-10 individual air conditioning units. how do i wire these services?

you dont need 3 phase you need a 220v or 110v single phase supply these units usually take about 10 to 15 amps each if this is central units then you can use 3 phase but not nescessary

My question is on the main 100 amp breaker it has one slot on each side of the breaker .so one hot wire goes on the right side and one goes on the left side ? its a little confusing because usually both...

A main breaker accepts two inputs which are 180 degrees out of phase. If this is in the US, then each phase is approx 110V relative to ground (or neutral) and the the two phases are approx 220V relative to each other. There are two hot bus-bars in the panel, running vertically one for each phase of the main breaker. If you look at how these bus bars are connected to the branch breakers, you will see that every-other breaker slot in the panel is connected to one phase or the other. So if you have a 220V branch breaker, say for the stove, this is really two breakers together, one for each phase. These 220V branch breakers do have output lugs right next to each other. The main breaker is similar in that it is also two breakers connected together. But because the main breaker is mounted at the top and is as wide (or nearly as wide) as both sets of branch breakers (down the left and down the right) it is generally more convenient to wire the inputs to the left and right side of this main breaker. But the location of the input lugs to the main breaker is arbitrary. There may be some models where the inputs are adjacent to each other. If you have any doubt, do a continuity test on the main breaker (while it is NOT installed) to confirm that that each input lug is connected only to one output clamp (that is, where it connects to it's bus-bar.) I hope this helps, please vote if it did. Good luck, Al K

Three phase house wiring, i want diagram with electrical symbols

What kind of diagram are you looking for? Large business and warehouses have 3 Phase. I've not heard of a house. but let me know. Typically 110 comes out of one breaker and one neutral wire (and saftey ground is 3rd) 220 comes out of two hot leads and one neutral wire (single phase). 3 phase comes out of 3 hot leads and one neutral but is still 220 volt.

Residential Electrical Wiring Current NEC

On a 120/240Volt single phase system is:

Black = 1st phase
Red = 2nd phase
White = neutral
Green or Bare = ground

3 phase is the same with the third phase being blue.
