Connect one wire to one side of the breaker and then connect the other wire to the other side. Securely tighten all screws on both sides of the breaker, making sure not to overtighten them.
If your electric scooter does not accept a rider on it, it is most likely due to a battery pack that is dropping power under load. The battery pack might need replacing or it can''t be recharged properly. Test the voltage of the battery pack. Perform a deep charge. Charge the battery for 48 to 72 hours.
A 12-volt circuit breaker, also known as a shortstop or auto reset circuit breaker, is good for providing safety to vehicle electronics is excellent to use when adding accessories such as additional lighting or any 12-volt device. If you want to learn how to install this car circuit breaker, here are the tools and guidelines to follow.
Safety First: Only a qualified electrician should perform the Jackery Manual Transfer Switch installation process in compliance with all applicable electrical codes. Notes: *To power your home circuit with the 2000 Plus or 3000 Pro, you will need a TT-30P to L5-30R power cord to hook up your 2000 Plus or 3000 Pro to the transfer switch.
Choose a circuit breaker size. We usually pick between 10A, 15A, 20A, 25A, 30A, 35A, 40A, 50A, 60A circuit breakers, and so on. This is how breaker sizing is done manually. The easiest way is to use a dynamic calculator. You simply input that wattage and the voltage, and the calculator will tell you what is the minimum size of a circuit breaker ...

Connect two fuses, one at the positive and one at the negative battery terminals. Also, during my research, I came across a post that advised to connect a fuse at the positive terminal since it would protect both circuit and the battery, but if the fuse is connected to the negative battery terminal, then it only protects the battery. Is this true?
