I would tend to agree with "Tripleauto". If you do not disconnect the electrical supply to the house, you run the risk of having 240 volts at up to about 75 KVA coursing through your body. Needless to say, before the transformer blows out or someone cuts off the power, your corpse will be mostly ash. Call the power company to co-ordinate having the power turned off while you or your electrician do the work. Once the power is off, swapping out the main breaker is a relatively simple job, assuming you can find an exact replacement. If there is no exact replacement, as in the panel is fairly old and the breaker is no longer available, you will end up having to replace the whole panel or add a 125 amp breaker in a separate enclosure in an accessible location between the meter socket and the breaker box, preferably within reach of the breaker panel. The International Residential Code requires a disconnct where there are more than six breakers needed to turn off all power to the dwelling. Check with your local Building Code office before doing anything.

SOURCE: installing a 220 circuit breaker
First you must have space for a double pole 30 amp breaker in your panel.
Otherwise is is almost the same as the one you installed before, exception is 2 hots both going to the breaker.
The green goes to ground. The white goes to neutral. The black and red go to the breaker.

Does the panel have room for the breaker?
Federal Pacific is a brand name panel and you may be able to find breakers at Home Depot, Menards, or Lowes if those stores are in your area. Bring the panel number to the store with you.
Here's a link for additional info:
There have also been some recalls for these panel breakers. See:

Sounds like you have a bad capacitor for your squirrel cage fan , now as for the a/c unit sounds like you have a direct short in compressor to ground or leg to leg , check all wiring to make sure that it is not grounding out or melted together.

Look on the label inside the door on the circuit breaker panel. It should list part numbers for acceptable breaker. The key is the part number. Bryant is now owned by Westinghouse. Murry is now owned by Siemens. While many breakers will fit in other brand panels, they are only code compliant if they are listed for that panel in which they are installed. Since names have changed go by the breaker numbers. If the breaker number you have is listed on the label then it would be ok. Breakers aren't that expensive, if you have doubt, go to your supply house that carries Siemens and buy breakers listed for your panel.
