Frequently Asked Questions
What size RV battery disconnect switch do I need?
The size depends on your maximum current draw. We recommend a switch rated at least 20% higher than your peak load. For most RVs with a single battery and modest appliances, a 100-amp switch is sufficient. For larger coaches with inverters, look for 250-300 amp continuous ratings. Always check your system’s maximum current from the inverter or converter.
Can I install a battery disconnect switch myself?
Yes, if you have basic electrical knowledge and tools. The switch is typically installed on the positive battery cable. Disconnect the battery first, then cut the cable and attach the switch terminals. Ensure all connections are tight and use proper gauge wire. If you are unsure, consult a professional RV technician.
Should I get a single-pole or double-pole switch?
For most RVs, a single-pole switch (interrupting the positive line) is sufficient. Double-pole switches interrupt both positive and negative, which is rare in RVs unless required by specific equipment or local codes. Stick with single-pole unless you have a specific need.
Are marine battery switches good for RVs?
Yes, many RV owners use marine switches because they are built to withstand moisture and vibration. Marine switches often meet ABYC standards, which align well with RV safety requirements. Just ensure the voltage and current ratings match your system.
How do I prevent corrosion on the switch terminals?
Apply a thin coat of dielectric grease or anti-corrosion spray to the terminals after installation. Choose a switch with sealed or weatherproof housing if mounting in an exposed area. Regularly inspect and clean terminals as part of your RV maintenance routine.
