Why we need to use the fuse?

图片
  Fuses have many unique performance characteristics, such as: Optimum Component Protection  Fuses reduce short circuit (fault) currents that flow to a low value by "current limitation". There is no need for complex short circuit calculations and no concerns about costly future upgrades due to system expansion with increased fault currents. Their compact size offers low-cost over-current protection for the highest short circuit levels. Safety  Fuses do not produce gas, flames, arcs, or other materials when clearing any value of over-current up to the highest level of short circuit. In addition, the speed of operation on high short circuit currents limits significantly the flash hazard at the fault location. Reliability  No moving parts to wear out or become contaminated by dust, oil, or corrosion, and no nuisance tripping. If a fault occurs, the fuse immediately operates in its predetermined manner or co-ordinates with other circuit components. The cause of the fault...

How to choose the correct RV fuse

  Before we start guessing which fuse for RV that we should use. It is important to know the Voltage, Current, and Power. These three items will always show up in your RV electrical circuits. Only when making clear of how they work you can never meet the potential problem. Understand Battery Wiring Firstly double confirm the voltage of your battery system in your camper. Generally there come 12V and 24V voltage. If you buy a pre-owned vehicle and have no idea of the house battery voltage, please follow this diagram to check the wiring and you can easily tell then answer. Parallel Battery Wiring & Series Battery Wiring What is the appliance power? The appliance will draw the power from the house battery. Check the specification label of the loads. You will find XXX WATTS, which is the parameter of the power. You will easily find it on the backside of the load like this 120VAC/12VDC freezer fridge. How to calculate the fridge power and current Start calculating! Now let’s measure...
