Amp hours to watt hours conversion calculatorĭisclaimer: Footprint Hero has made every effort to ensure that the results generated by this fuse sizing calculator are correct and valid for the provided user inputs.Consult the NEC and its guidelines for overcurrent protection. Calculate fuse size following NEC guidelines.Fill out our calculator at the top of the page and it will provide a recommended fuse size based on your inputs. To calculate the right fuse size in this example, you can either: You consult your inverter’s documentation but don’t find a recommended fuse size. (Many inverters have built-in fuses, but let’s assume in this scenario that yours doesn’t.) Let’s say you’re designing a solar power system and you want to place a fuse between your inverter and battery bank. Only calculate fuse size yourself when there is no recommended fuse size, and even then only if you possess the appropriate working knowledge and understanding of electrical systems. Note: Always use the fuse sizes recommended by the manufacturer when available.

How to Choose a Fuse Sizeīecause it’s recommended by the manufacturer, that’s the size you’ll use.Įasy! 2. We do not recommend using it for other types of electrical systems. Note: This calculator is designed for solar power systems. Consult Section 310.15(C)(1) of the NEC for adjustment factors for more than three current-carrying conductors. There are not more than three current-carrying conductors in the raceway or cable, including spare conductors.If no wire temperature rating is selected, a rating of 75☌ (167☏) is used by default. The current flow in amps is a continuous load.

Consult Section 310.15(B) of the National Electrical Code (NEC) for ampacity correction factors where the ambient temperature is other than 30☌ (86☏).

Wiring is installed in a 30☌ (86☏) ambient temperature.

This fuse calculator makes the following simplifying assumptions: If you’re using aluminum wire, use a thicker wire.

Note: Based on your inputs, we recommend this fuze size for copper wire only.
