Re: how to increase the power supply
A 100 amp service is usually more than enough for most homes except fully electric homes. If you trip a breaker it is because you are overloading that one circuit. If your house is wired with 14 ga wires, the breaker should be rated at 15 amps. To increase the allowable current the wiring would have to be replaced. For instance replacing a 14 ga cable with a 12 ga cable would allow you to use a 20 amp breaker. If you just have to many outlets on the same circuit, adding circuits will help. You can have more circuits added by adding a sub-panel and running the additional wiring. It is doubtful that you will get to the point that you trip the main breaker, most homes average less than 60 amp high draw unless you have electric heat.
