Will upgrading to a 400amp from 200amp main service circuit breaker cure power drops NOT outages just drops in power amperage I currently have 200amp main service and am considering upgrading to 400?

Increasing the ampacity of your service will not cure power drops. If your main breaker has not tripped then your connected load is under 200 amps. The power drops are the responsibility of your utility company. They are required to keep the voltage within a 10% tolerance. When asked some utility companies will connect a recording volt meter to your line to check your claim of low voltage. Call them. Log the time when the power drops over a week. If they will not monitor your line give them the list of the power drops that you recorded as this may help them. You are probably at the end of the line and connections up stream are probably the cause of your power fluctuations.
