Does a switch need a fuse?

The consumer unit will either have a trip switch or a fuse box. If a fault develops, a switch is tripped and the circuit is broken, modern electric circuits are fitted with a circuit breaker fuse system.

Do I need a fuse between battery and trolling motor?

Installing a fuse or circuit breaker on your trolling motor is important to prevent damage if your motor becomes stressed or overheated.

Why is the fuse before switch?

With the fuse first, any fault in the switch is protected against. With the switch first, the fuse holder is isolated when the device is switched off to make replacing the fuse safer.

What comes first switch or fuse?

You want any amp fault including the switch to cut off power from anything downstream. Suppose a wire to the switch broke off, I know it’s not likely but you don’t want live ac in the case just because your fuse wasn’t before the switch. Fuse should ALWAYS come before the switch.

What size fuse do I need for a trolling motor?

What is this? To be exact, a 50-amp circuit breaker for a trolling motor and a 60-amp circuit breaker for a trolling motor should always handle more than 10% of the current requirement of the motor.

How do you choose the size of a fuse?

The voltage and current ratings are paramount. A fuse should be de-rated by 25% at room temperature, meaning if there is a 7.5 amp circuit, a 10 amp fuse should be used at 25˚C. Voltage ratings on a fuse can be higher than the voltage on the circuit, but not lower.

Why the fuse and switch must be on live wire?

The fuse is connected to the live wire so that the appliance will not become charged (have a potential difference of 230 V) after the fuse has melted due to excessive current. Fuses must be fitted onto the live wire so that when it blows, it will disconnect (isolate) the appliance from the high voltage live wire.

How many amps does a 12V trolling motor draw?

The Minn Kota Endura C2 55 Transom – mount 12V 55 lb. Thrust Trolling Motor has a max amp draw of 52 amps/hr but only 5 lbs more thrust.

Why do you need a circuit breaker for a trolling motor?

A circuit breaker protects the electrical system of your trolling motor, as well as your battery, from damage due to electrical current overload or short circuits. Circuit breakers “trip” (cut power) above a specific amperage, so the motor and battery will not suffer damage from electrical overload.

Is circuit breaker necessary for trolling motor?

It is highly recommended that a circuit breaker or fuse be used when installing a trolling motor.
