Square D QOT1515CP 15A Tandem Circuit Breaker 120/240V

Product Description

The Square D QOT1515CP is a single-pole tandem circuit breaker rated at 15 amps and designed for use in QO-style load centers equipped with pan rail slots. Each tandem unit occupies one-half space per pole, allowing two 15-amp circuits to fit within a single breaker slot. This makes it a practical solution when a panel is nearing capacity and additional circuits are needed without replacing the load center. Licensed electricians install this breaker during panel upgrades, service changes, and circuit additions in both new construction and retrofit applications.

This breaker is intended for residential and light commercial electrical panels that accept QO-style tandem breakers. It is specifically listed for use in current-model Square D load centers that feature pan rail slots designed to accept tandem-style units. The 120/240-volt rating covers standard single-pole branch circuit applications throughout a dwelling or commercial space. The bulk packaging format, with 10 units per package, suits contractors stocking a service vehicle or supply room.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Always shut off main power at the service disconnect and verify the panel is de-energized before working inside a load center. Confirm that the target load center has pan rail slots rated for tandem breakers before installation, as not all QO panels accept tandem units in every position. Follow the load center's interior directory and breaker position chart to ensure the tandem breaker is seated in a slot that permits tandem use.
