Protecting the eGauge with inline fuses

As long as it is permitted by code, an inline fuse can be used to protect the eGauge. We suggest using a quick disconnect fuse block to allow the eGauge to be power cycled for troubleshooting if needed. A rating of 15A is suggested, but a larger or smaller fuse (between 5A and 50A) is also acceptable.

It is important to provide the end user with a reliable means of power cycling the eGauge.  This is generally the first step in any sort of troubleshooting process.  A fuse block which exposes the end user to line voltages is generally not adequate.
