Buying Guide

Match amperage to circuit load

Choose breakers with ratings (e.g., 15A, 30A, 60A, 90A, 100A) that match the circuit's expected continuous and peak loads to avoid nuisance trips or overloads

Select the correct pole configuration

Use single-pole breakers for standard 120V circuits, twin single-pole for paired RV circuits, and double- or three-pole breakers for multi-wire or 240V circuits to ensure proper phase handling

Prefer established manufacturers

Brands like Siemens and RecPro have consistent build quality and documented compatibility with many panel systems, which reduces installation uncertainty

Confirm physical and electrical compatibility

Verify the breaker form factor (QP style), terminal type, and panel model compatibility before purchase to ensure a proper fit and secure connection

Consider rating and pack options for value

Buying individual breakers versus multi-packs (for example, 3-packs) may affect per-unit value—choose based on how many spares or replacements you need
