I'm trying to figure out how to get 220 volts for a dryer installation. The house just has 110 volt outlets. My question is, would I be able to tap into the 220 v used for the central air, and get the 220 volt I need for the dryer? Right now the central air breaker is set at 30A each.

What are the alternatives without calling for a electrician? Is there anything out there that can convert 110 to 220 for high power usage such as the dryer?

this sounds complicated, i'll call a certified pro....

In a 110 volt ckt, how does the ground work (green or bare wire) ?

you cannot hook it to the ac circuit or change a 110 outlet to 220 volts...you need to get a 30 amp breaker for your main power box...some 10/3 with ground...and an outlet that matches the plug on your dryer...the wire will have 4 wires in it red (hot) black(hot) these go to breaker..white Neutral.connects where all the other white wires are in your power box..bare or green ground. connects with all the other bare or green wires are in your box...the outlet will have instructions on how to connect it....if you cannot do this call an electrician...Be safe be sure to turn main power breaker off before removing cover to your power box....normally all electric dryers are 30 amp unless otherwise specified on their nameplate and can be wired with 10/3 wire according to the national electric code 240.4, also nec 310.15 d says #10 wire maximum amperage rating is 40 amps on non plug and receptacle circuits...never put a dryer on a 40 or 50 amp breaker unless it requires you to do so...always check the amp draw on the dryer...the bare or ground wire will carry any voltage from any electrical short to frame to the outside grounding on your electrical system until the breaker trips... it is a safety for any voltage and doesnt carry any power otherwise....
Why don't you buy a 110/220 transformer, just check the Amps on the dryer and get an appropriate one.
According to my knowledge, if on the dryer you have 5 Amps that means 5X220=1100 Watts, this should be balanced when you use the 110, so 1100/110=10 Amps
As a conclusion, if the dryer consumes 5 Amps on 220 it will consume 10 Amps on the 110 so you will need to have a 15 Amp circuit breaker on the line of the dryer, at the 110 side.
the answer to your question as far as tapping from your ac is no,the dryer pulls to much power so does the ac,it is against the nec code,you need to run a new line to your dryer go buy electrical wire rated at 30 amps and you will need a double 30 amp breaker, the wire has to have 3 wires one white which is neutral, one black which is 110 volts and one red which is the other 110 volts this would give you 220 volts.
