A four-circuit load center rated at 60 A for single-phase 120/240 VAC distribution. It occupies the middle ground between basic 2-way units and larger 6-way panels, offering enough breaker positions to separate lighting, receptacle, and dedicated appliance circuits in small homes and commercial units.

Features

01/

Plug-In Breaker Design

Four 1-inch plug-in breaker stations accept standard branch devices without tools. This capacity allows electricians to dedicate individual circuits to lighting, general outlets, and small motor loads such as garage door openers or water heaters.

02/

Heavy-Duty Steel Construction

Fabricated from 0.5–2.0 mm cold-rolled steel sheet, the enclosure provides the structural mass needed to support four active breakers and their conductors without flexing or distortion during long-term wall mounting.

03/

Matte Powder-Coated Finish

The steel shell receives a uniform polyester powder layer that cures to a matte surface. This coating tolerates the occasional scuffs and humidity fluctuations common in garages, basements, and back-of-house commercial areas.

04/

Optimized Interior Layout

Wider than the 2-way model, the interior cavity is laid out to keep four conductor bundles separated while maintaining proper bending radii. The extra width reduces the chance of wire overlap and simplifies future circuit additions.

05/

Dual Mounting Options

Flush mounting sets the panel face even with drywall for a built-in appearance in finished hallways and kitchens. Surface mounting projects the box slightly forward, making it practical for unfinished basements, masonry walls, or retrofit jobs where recessing is impractical.

06/

Multi-Directional Cable Entry

Knockouts are formed on the top, bottom, left, right, and rear walls. Feeders and branch lines can therefore approach from the shortest route, minimizing the number of conduit offsets and elbow fittings required in crowded stud bays.

07/

Grounding & Safety Compliance

An aluminum bus bar assembly provides both neutral and equipment grounding points. The bar is sized for the 60 A main rating and accepts the gauge of copper grounding conductors typically run with branch circuits in residential and light commercial wiring.

Key Applications

Single-family homes and apartment sub-panels

Small offices and neighborhood retail shops

Garage and basement electrical upgrades

Light industrial control stations

Service entrance equipment replacements

FAQ

Q1: Does the 4-way panel accept tandem or twin breakers?

A: The four positions are designed for standard 1-inch plug-in breakers. Tandem devices may fit physically, but the bus stabs and enclosure labeling should be verified against the breaker manufacturer's compatibility chart before installation.

Q2: Is 60 A sufficient for a small café or retail shop?

A: For a small retail space with lighting, outlets, and a coffee machine, 60 A is typically adequate. If the space adds kitchen equipment, HVAC, or EV charging, consider the GPD6 or GPD8.

Q3: Why does this series use cold-rolled steel instead of electro-galvanized steel?

A: Cold-rolled steel provides a smoother surface for powder coating and maintains dimensional accuracy during stamping. The finished panel is then treated for corrosion resistance, making it suitable for dry indoor environments.

Q4: Can the cover be removed while the panel is energized?

A: The screw-fastened cover can be removed with a screwdriver to access breakers. However, only qualified personnel should open the panel, and local lockout/tagout procedures must be followed.

Q5: What wire size should I run for the 60 A main lugs?

A: For a 60 A main, copper feeders are typically 6 AWG or 4 AWG depending on insulation type and run length. Always confirm with NEC or your local authority having jurisdiction.
