HOMT3020 - Square D - Molded Case Circuit Breakers 30 Amp - 2 Pole - 120 Volt

Square D HOMT3020 Homeline Tandem Plug-In Circuit Breaker — two single-pole thermal magnetic circuit breakers in a tandem configuration that occupies only one HOM pole space in your Homeline load center, effectively doubling circuit capacity without requiring a panel upgrade.

Why Choose the Square D HOMT3020?

The HOMT3020 is engineered for fast installation and superior circuit protection. Each pole operates independently — individual switching and tripping action means one circuit can trip without affecting the other. Ideal for residential panel upgrades, additions, and service panel expansions where pole space is limited.

What Is a Tandem Circuit Breaker?

A tandem breaker (also called a twin or half-size breaker) contains two separate circuit breakers side by side in a single-pole-width housing. The HOMT3020 allows you to add or replace circuits in a Square D Homeline load center without adding panel space — critical when your panel is full but code requires additional circuits.

Common Applications

• Residential panel upgrades with limited pole space
• Adding 20A branch circuits (lighting, outlets, appliances)
• Adding 30A circuits (dryers, EV chargers, water heaters)
• Homeline load center expansions and retrofits

Compatibility

Designed exclusively for Square D Homeline (HOM) load centers. Verify your panel's tandem breaker acceptance before installation — not all HOM positions accept tandem breakers. Refer to your load center's breaker acceptance chart.
