Empty Space Filler Panel Distribution Box

Empty space filler panels are used to safely cover unused breaker slots in distribution boxes, preventing accidental contact and maintaining panel integrity.

Purpose and Benefits

Filler panels, also called blank plates or filler plates, are designed to cover empty spaces in load centers or panelboards. They enhance safety by preventing accidental contact with live electrical components, improve the panel's appearance, and help maintain compliance with electrical codes. They are commonly used when breakers are removed or when a panel has unused slots.

Types and Sizes

Filler panels come in various sizes and configurations depending on the panel type:

• GE Filler Plate Kit: Includes 1/2 inch and 1 inch plates for rectangular breaker knockouts, made of high-impact plastic for safety .
• ABB Spectra Series: Plug-in or bolt-on filler plates with support brackets, designed for vertical panel spaces of 1 3/8 inches (1X), suitable for Spectra+ and Spectra Power panels .
• Schneider Electric I-Line HLW1BL: Blank plates for 1.5-inch wide spaces, compatible with breakers without Micrologic trip .
• Platt Electric Supply: Offers 1", 3/4", and 1/2" filler plates for various load centers including BR, CH, and PowerMark series, with full-width options for larger panels .

Installation

Filler panels can be plug-in or bolt-on, depending on the panel design. Plug-in plates are inserted into the slot and held in place by the panel's structure, while bolt-on plates require screws or brackets for secure attachment. Some kits include support brackets and hardware for proper installation .

Material and Durability

Most filler panels are made from high-impact plastic or durable thermoplastics, ensuring long-term safety and resistance to wear. Certain panels, like IP66-rated distribution boxes, are designed for outdoor or industrial use, offering protection against dust and water ingress .

Selection Tips

• Check panel compatibility: Ensure the filler plate matches the brand and series of your load center (e.g., GE PowerMark, ABB Spectra, I-Line, BR or CH series).
• Measure slot size: Verify the width and height of the empty breaker space to select the correct plate size.
• Consider installation type: Choose plug-in for easy installation or bolt-on for a more secure fit.
• Material and rating: For industrial or outdoor panels, select plates with appropriate IP or UL ratings. Using the correct filler panels ensures safety, compliance, and a professional finish for your electrical distribution box.
