What is a 30 amp fuse used for?
A 30-amp screw-in fuse is most commonly used for circuits supplying electric clothes dryers or air conditioners. These circuits are wired with 10-gauge wire.
Can I use a 30a fuse in a 20a?
If you put a 20 Amp fues in a 30 Amp circuit, it will blow before you know it. Replacing a 20-amp fuse with one rated at 30 Amp is dangerous because it may not blow soon enough and damage an electrical component or start a fire.
Can I replace a 13A fuse with a 5A fuse?
Re: Can I use a 13A fuse in a 5A plug ? No. You must use a 5A fuse. Using A 13A fuse is a fire risk.
Can you use a fuse with amp higher?
In general, NO. Replacing a fuse with a higher-amp fuse is a very bad idea and can lead to fires. Fuses (and circuit breakers) are rated such that they blow or trip before any part of the circuit gets to a dangerous current.
Is 30 amps a lot?
The key to living on 30 amps is to not exceed the amperage of an individual circuit, and to not exceed a total of 30 amps at any given time. With a better understanding of your RV’s electrical system and some simple electrical formulas you can live comfortably on 30 amps with little to no problems.
Why does my ECM 1 fuse keep blowing?
If the wires leading to the O2 sensor rub against the exhaust, it creates a ground; once the O2 sensor is grounded, the fuse to the ECM 1 blows. The O2 sensor must be installed in a different place to ensure the wires do not short-circuit.
When do you need to replace the ECM power relay?
If there is no power when the key is inserted, the engine will not start, or the battery is dead, you may need to replace the ECM power relay. 1. No power when the key is inserted 2. Engine will not start 3. Battery drain or dead battery Average rating from 130,153 customers who received a Vehicle Engine Electrical Inspection.
Why does my ECM 1 make a clicking noise?
The voltage or amps surge, causing the ECM 1’s fuse to blow. When the starter fails you will hear a clicking noise or the engine will be hard to start.

What causes a battery to go dead on an ECM?
Battery drain or dead battery A failed ECM power relay can also cause a battery drain or dead battery. If the relay shorts it can leave power on to the computer, even when the vehicle is turned off. This will place a parasitic drain on the battery, which will eventually cause it to go dead.
