Hearing aid batteries last anywhere between five and 14 days depending on the above factors. You will know it's time to replace your hearing aid batteries when the aids start beeping. One solution to save money and make batteries last longer is to purchase rechargeable batteries.
To clarify: you have a main panel with a 60A breaker. That breaker feeds a subpanel which has a 100A main breaker and then some smaller circuit breakers in the sub-panel. If more than 100 coulombs of charge per second flow through the sub-panel main breaker, it will trip and cut power to the subpanel breakers.
Best Answer: Each circuit in the panel is designed to trip if the load goes over that amperage for a specific amount of time. They are limited by the main device breaker as to how many amps you can push through them all. The main service amperage is based on the meter socket first and foremost.
