The SQDQO2030 is a reliable Square D 20/30 Tandem Breaker designed for efficient space-saving in your electrical panel. This dual-function circuit breaker combines two circuits into a single slot, optimizing performance and convenience. Ideal for residential and commercial applications, it ensures protection against overloads and short circuits, delivering peace of mind.
A tandem (or twin) breaker like the QO2030 fits into a single 1-pole slot in your panel but provides two separate, independently protected circuits — in this case one 20A circuit and one 30A circuit. A standard 1-pole breaker only provides one circuit per slot. This makes tandem breakers a great space-saving solution when your panel is full but your loadcentre supports them.
Not necessarily. QO loadcentres are CTL (Circuit Total Limiting) rated, meaning only specific slots are approved to accept tandem breakers — these are indicated on your panel's interior directory label or bus schedule. Installing a tandem in a non-approved slot is a code violation. Always check your panel's label or consult a licensed electrician before installation.
The Square D QO2030 tandem breaker can be difficult to source through regular retail channels. Northern Breaker Group specializes in exactly these kinds of hard-to-find and obsolete breakers — contact us for availability and we'll get you a quote promptly.
