Can you install a 240v outlet for a stick welder near your panel if it has slots available for a circuit breaker?

Simple answer is yes. But you need to first determine if your breaker can handle it, not just because you have an empty slot. You have to total up amps being used and check rating for your box. If it can handle it then it is a sinch to install


If you install a 30A 240V GFI breaker will this be ok or will the cycles the dryer has prematurely fail the breaker?

I suspect you mean GFIC breaker. The dryer will not cause the breaker to fail.

You can't.


What would happen if a 240V breaker was on and someone attempted to turn on the clothes dryer?

Don't understand this question. If the breaker is on, then the dryer would function normally, if the breaker your are referring to is the one for the dryer. If the breaker is off then no function. A dryer runs on 220.


How do you wire a 15 amp 120V breaker in a 240v 30 amp breaker panel?

Look to see if the 30 amp panel is fed with a two wire or a three wire. If it is a two wire then you are out of luck. If the panel is fed with a three wire then the panel should have the neutral terminated in the panel. It is this neutral that you need for 120 volt connections. You didn't state how many panel slots there are in the panel. If you are able install a 15 amp breaker into the panel and connect the wires going to the load. The black wire will go to the breaker and the white wire will go to the neutral bar in the panel.

Have 240v 30amp breaker need to connect a 240volt 40 amp cooktop can you do this I have a 103 600volt wire the cooktop power supply requires 240volt 4 wire 60 hz?

Yes you can. As long as you don't use 40 amps. The 30 amp breaker may kick off if you use all things at once. So you are well protected but not up to code. The 4th wire required for the new stove is probably a ground fault wire. So run a new cable or cook slower.
