Eaton Corporation BD2020 Tandem Circuit Breaker 20A 120V

Product Description

The EATON CORPORATION BD2020 is a single-pole tandem circuit breaker rated at 20 amps and 120 volts. Two 20-amp breaker poles are riveted together inside a 1-inch case, allowing two circuits to occupy a single breaker slot. This configuration is commonly used when a panel is at capacity and additional circuits are needed without adding a new panel. Licensed electricians install this breaker during service upgrades, panel expansions, and circuit additions in residential and light commercial applications.

The BD2020 is suited for residential load centers and light commercial panelboards where space is limited and dual-circuit capacity is required in a single slot. Its tandem design allows two independent 120-volt branch circuits to share one breaker space. Each pole provides individual overcurrent protection. This breaker ships in bulk packaging with an individual UPC bar code per unit, making it practical for distributor and contractor stocking.

Key Features

• Dual 20-amp single-pole circuits housed in a 1-inch tandem case
• Rated at 120 volts for standard branch circuit protection
• Riveted tandem construction keeps both poles aligned and secure
• Individual UPC bar code included for inventory and jobsite tracking
• Bulk packaging — 10 units per package for contractor stock orders

Compatibility

Designed as an OEM-style tandem replacement breaker for compatible residential and light commercial load centers that accept single-inch tandem breakers. Verify panel compatibility and tandem-breaker acceptance with the panelboard manufacturer before installation.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NFPA 70 (National Electrical Code) and all applicable local codes. De-energize the panel and verify the main breaker is off before handling any breaker or bus connections. Confirm the load center is listed to accept tandem breakers in the intended slot — not all slots in a given panel are tandem-rated. Do not force the breaker into a slot that does not accept tandem devices.
