Factors to Consider
As I shopped around, I realized there were several key factors to consider when choosing the right disconnect switch for my needs:
- Amperage Rating: It’s crucial to select a switch that can handle the current of my vehicle. I aimed for a rating that exceeded my car’s maximum amperage to ensure safety and efficiency.
- Material Quality: I wanted a switch made from durable materials, as I knew it would be exposed to the elements. I looked for corrosion-resistant options to ensure longevity.
- Ease of Installation: I wasn’t looking for a complicated project, so I chose a switch that came with clear instructions and all the necessary mounting hardware.
- Size and Compatibility: I measured the space in my vehicle to ensure that the switch would fit. Compatibility with my battery type was also important.
