What is the acceptable maximum amperage per brake for electric trailer brakes?

The maximum amperage per brake for electric trailer brakes is important for ensuring the proper operation of the braking system. Electric trailer brakes are engineered with specific current ratings by the manufacturer, and exceeding these ratings can lead to overheating and premature failure of the brakes.

The correct understanding is that acceptable amperage levels for electric trailer brakes should generally not exceed manufacturer specifications by significant margins. It's critical to follow manufacturer guidelines for safety and performance. If acceptable amperage is set too high or too low, it can compromise the brake's ability to function effectively under load.

In this case, the selection indicating that the acceptable amperage can be "more than 20% or more than 30% below the manufacturer’s maximum current rating" is accurate in reflecting that exceeding or dropping significantly below the specified range can lead to issues. Thus, maintaining a proper amperage level within the stated parameters is crucial for both safety and adherence to inspection standards.

Keeping the amperage within recommended limits ensures the reliability of the braking system while also reflecting compliance with the regulations governing electric trailer brakes.
