Car Air Compressor Fuse Size: A Comprehensive Guide185

Introduction

A car air compressor is an essential tool for maintaining optimal tire pressure. It is powered by the vehicle's electrical system and requires a fuse to protect against electrical overloads. Choosing the right fuse size is crucial to ensure the safe and efficient operation of the air compressor.

Factors to Consider

The following factors need to be considered when determining the appropriate fuse size for a car air compressor:
Amperage Draw: The air compressor's amperage draw is the amount of current it consumes during operation. This value is typically specified in the manufacturer's instructions.
Fuse Rating: The fuse's rating is the maximum amperage it can handle before blowing. It should be slightly higher than the air compressor's amperage draw to allow for surges.
Fuse Type: There are different types of fuses available, including blade fuses and glass fuses. The type of fuse required depends on the fuse holder in the vehicle.

Calculating Fuse Size

To determine the appropriate fuse size, follow these steps:
Locate the amperage draw of the air compressor in the manufacturer's specifications.
Multiply the amperage draw by 1.5 to account for surges. For example, if the air compressor's amperage draw is 12 amps, multiply it by 1.5 to get 18 amps.
Select a fuse with a rating slightly higher than the calculated amperage. In this case, a fuse rated for 20 amps would be suitable.

Fuse Location

The fuse for the car air compressor is typically located in the vehicle's fuse box, which is usually under the dashboard or hood.
