Blue Sea AC Isolation Panel Back Cover, 7-1/2 x 10-1/2x3
Blue Sea AC Isolation Panel Back Cover, 7-1/2 x 10-1/2x3
ABYC Compliant Rear Enclosure - Approx. 191x267x76mm Drillable Plastic

DESCRIPTION
Reliable Electrical Insulation and Mechanical Protection for Exposed Panel Backs
Installing an electrical switch panel often leaves the rear terminals, busbars, and wiring exposed inside an adjacent storage locker, cabinet, or console. In dynamic environments such as marine vessels, caravans, and off-grid service vehicles, shifting gear can easily snag on loose wiring or make accidental contact with live terminals. The Blue Sea Systems 4028B AC Isolation Panel Back Cover is purpose-built to eliminate these hazards, providing a dedicated barrier that ensures both mechanical protection and vital electrical insulation for the rear of your panel installations.
Engineered for ABYC Compliance and System Safety
When working with high-voltage alternating current (AC) alongside low-voltage direct current (DC) systems, strict separation and insulation standards are critical. This isolation cover is engineered to meet American Boat and Yacht Council (ABYC) safety requirements for electrical panels housing combined AC and DC loads. Unlike makeshift enclosures or standard project boxes, this purpose-designed cover mitigates the risk of accidental short circuits, electrical shocks, and terminal damage caused by stowed equipment shifting in rough conditions.
Key Features and Installation Benefits
- ABYC Compliant Safety: Meets stringent safety requirements for panels integrating combined AC and DC circuits, reducing the risk of accidental contact with live AC components.
- Customisable Cable Routing: Manufactured from a durable, lightweight insulating plastic with drillable side walls, allowing installers to create custom cable entry and exit points tailored to specific wiring loom layouts.
- Integrated Mounting Flange: Features a peripheral flange with four pre-drilled corner mounting holes, ensuring a stable, flush fitment directly over the rear of the panel.
- Generous Enclosure Dimensions: Measuring 7-1/2" x 10-1/2" x 3" (Approx. 190.5mm x 266.7mm x 76.2mm), the cover provides ample internal depth to accommodate heavy-duty circuit breakers, meters, and rear-mounted wiring harnesses without cramping.
- Durable Textured Finish: Constructed from robust, non-conductive material designed to withstand the rigours of marine lockers and mobile utility compartments.
Versatile Applications Across Marine and Off-Grid Setups
While originally designed to meet the demanding standards of the marine industry, the 4028B isolation back cover is equally suited to custom RV, caravan, and off-grid power canopies. Whenever a distribution panel is flush-mounted into a bulkhead or partition wall where the rear protrudes into a functional storage space, this cover provides a clean, professional finish. Because the side walls are easily drilled with standard hole saws or step bits, you can effortlessly fit cable glands, split tubing, or custom grommets to maintain a tidy and secure wiring harness.
