Buying Guide

Match amperage to your panel

Choose a transfer switch with an amperage rating (e.g., 63A or 100A) that matches your generator and main breaker capacity to avoid overloading circuits

Manual vs. automatic operation

Decide whether you need an automatic transfer function for hands-free switching or a manual switch for simpler, lower-cost control

Check voltage compatibility

Confirm the switch supports the voltage you use (110V, 220V, or dual-power) so connected appliances receive correct power

Look for safety and mounting features

Prefer models with UL listing or robust mounting options like din-rail to ensure safe installation in outdoor or garage locations

User feedback and display aids

Consider units with LED displays or strong user ratings to simplify diagnostics and confirm proper operation during outages
