Tandem Circuit Breaker · 20/20A · 1-Pole Plug-In for QO Load Centres · Square D QO2020
SKU: QO2020
20/20A tandem thermal-magnetic circuit breaker for Square D QO load centres, providing two 120V single-pole circuits in one panel space. Suitable where the load centre is specifically approved for tandem breakers; typical 20A branch circuits use #12 AWG copper, and actual conductor and breaker selection must follow local electrical code and panel labelling.

What this product is for
This Square D QO2020 is a tandem miniature circuit breaker used to add two 20A single-pole branch circuits while occupying one panel space in a compatible Square D QO load centre. It is a plug-in, thermal-magnetic breaker rated 120/240 VAC with 10 kA interrupting capacity.
Use for
Use for space-limited panel expansions in approved single-phase QO load centres, where two 20A 120V circuits are needed in one slot. Common applications include general receptacle or dedicated branch circuits where the panel directory and load centre labelling permit tandem breakers.
Avoid for
Do not use in panelboards or in load centres that do not specifically allow tandem breakers in that position. Do not use as a 2-pole common-trip breaker for 240V loads, and do not assume tandem compatibility based on physical fit alone.
Best for
Best for electricians adding capacity to an existing Square D QO residential panel without installing a larger load centre. It is also a practical replacement when the panel schedule and manufacturer labelling call for a QO2020 type tandem breaker.
Installed in
Installed in compatible Square D QO single-phase load centres and lighting panel applications that accept tandem breakers. The breaker occupies one 3/4 in (19 mm) panel space and mounts plug-in style.
Why this product exists
This breaker exists to increase circuit count in approved QO load centres without consuming two full breaker spaces. For service work and renovations, that can reduce panel changeout requirements when only a small amount of additional branch capacity is needed.
Compared with similar products
Compared with a standard full-size 1-pole breaker, this tandem design provides two independent 20A circuits in one space. Compared with a 2-pole breaker, it does not provide common-trip protection for 240V loads. As a rule of thumb, 20A branch circuits are commonly paired with #12 AWG copper conductors, but actual conductor sizing, termination suitability, and circuit application depend on installation conditions and local electrical code.
