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. The fuses should be rated at 15A.
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.
