Full-Plastic Recessed Distribution Box: Key Features & Typical Use
No Metal, So No Rust
Both the panel and the enclosure are moulded from ABS flame-retardant material, so the box has no metal parts to corrode. That makes the LYC1 a practical choice in damp basements, garden lighting circuits, pool plant areas and coastal properties, where even a painted metal box tends to fail at the door edge within a few years.Light Enough for a Single Installer
A full-plastic body is substantially lighter than an equivalent steel enclosure, which matters for a recessed box that has to be held in a wall opening while it is levelled and fixed. One electrician can handle the larger sizes without assistance, and there is no risk of a painted surface being scratched during installation.3 to 36 Ways
The range runs from the compact LYC1-3 at 138 x 94 x 83 mm, suitable for a single lighting circuit, up to the LYC1-36 at 410 x 345 x 88 mm for a small commercial distribution board. A flip-top observation window allows breaker status to be checked without opening the box, so a tripped garden or corridor circuit can be identified at a glance.Flush Installation with Standard Breakers
The recessed design keeps the board flat to the wall, which is important where the box is visible in a corridor. Each unit is supplied with the panel, the neutral and earth busbar set, a DIN rail and the enclosure, and accepts standard DIN-rail circuit breakers, so a plastic enclosure does not mean a proprietary internal arrangement.Full-Plastic Recessed Distribution Box Specifications & Technical Data

LYC1 — Full-Plastic Recessed Distribution Box
In a damp basement, a garden lighting circuit or a pool plant area, a metal distribution box usually fails at the door edge long before the electrics inside do. The LYC1 removes that failure mode by moulding both the panel and the enclosure from ABS flame-retardant material, so there is no metal to corrode.This box is also called a plastic consumer unit, an all-insulated distribution box or a rust-free breaker box, and it is compared with metal-backed boards and with metal-clad outdoor boxes. The reason to choose it is corrosion, not cost: in damp basements, garden circuits, pool plant areas and coastal properties a metal enclosure eventually fails at the door edge, while an all-plastic body has nothing to corrode.Being full plastic also makes the box light. A recessed enclosure has to be held in the wall opening while it is levelled and fixed, and a lighter body means one electrician can manage the larger sizes, with no painted surface at risk of being scratched during installation.The range covers 3 ways up to 36 ways, from the LYC1-3 at 138 x 94 x 83 mm to the LYC1-36 at 410 x 345 x 88 mm overall, and the recessed design keeps the board flat against the wall. A flip-top window allows breaker status to be checked without opening the enclosure, and standard DIN-rail breakers fit the supplied rail.Factory-Direct Full-Plastic Recessed Distribution Box Manufacturer & OEM / ODM
We Manufacture, You Brand
LYE Technology (Zhejiang) Co., Ltd. is a national high-tech enterprise and manufacturer in Wenzhou, China: sheet-metal fabrication, welding, powder coating, busbar machining and final assembly run on our own factory lines, and every unit is function-tested before it leaves the works. A LYC1 Full-Plastic Recessed Distribution Box that reaches your site carries the routine test behind it, not just the rating on the nameplate.We are one of the Top 10 Brands of China's small power distribution boxes and a drafter of national standards in this category, and we hold ISO9001, ISO14001, ISO45001, CCC, CE and TUV certification. Because we are the manufacturer rather than a trading company, our sales engineers quote from your drawing in factory-direct terms, and OEM or ODM work is produced on the same lines as our standard products.For the LYC1 we mould the panel and enclosure as one unit in our own works, so the wall aperture and the internal rail position are fixed together rather than assembled from separate parts.- OEM branding — custom colours, laser marking and your own project or retail packaging, applied at the factory.
- ODM options — ratings, configurations and internal layouts built around your drawings or single-line diagram.
- Certification — ISO9001, ISO14001, ISO45001, CCC, CE and TUV, with test documents supplied per project.
- MOQ — flexible quantities for a project or a trial order, with mixed types welcome in one shipment.

Full-Plastic Recessed Distribution Box Buying Guide from the Manufacturer
The LYC1 is usually chosen for corrosive or damp locations, so the order settles on size and circuit count. These are the points we confirm.
- Count the circuits to fix the way count from the range available.
- Confirm the wall opening dimensions and the flush depth available for the recessed body.
- Confirm the environment, since a damp or coastal location is the reason to choose plastic over metal.
- Confirm the breaker types to be fitted so the rail and depth suit them.
- Send the circuit schedule, wall construction detail and any labelling requirement.
- Approve the drawing, then production and dispatch.

What is a full-plastic distribution box?
It is a distribution enclosure in which both the panel and the enclosure are moulded from insulating plastic, so there is no metal body to corrode. The LYC1 uses ABS flame-retardant material moulded as one unit, covers 3 to 36 ways, mounts recessed so the board finishes flush to the wall, and has a flip-top observation window for status checks.When should I use a plastic rather than a metal distribution box?
When the position is damp, humid or aggressive. Metal enclosures fail at the door edge, hinge and gland plate once the coating is damaged, and once moisture reaches the substrate the box rusts from the inside. Plastic is also notably lighter, which matters for a recessed box that has to be held and levelled in a wall opening by one person.What is the difference between a recessed and a surface-mounted plastic box?
A recessed box sits inside the wall so only the front is visible, which suits corridors and finished rooms but requires the wall to be cut. A surface-mounted box fixes onto the wall and needs no cutting, which suits retrofits. The LYC1 range is recessed mounted, so it is normally specified during construction or renovation rather than as a retrofit.Who manufactures plastic distribution boxes?
Suppliers range from general enclosure manufacturers to specialists in moulded products, and the differences show in the moulding quality and the flame-retardant grade rather than in the basic shape. Ask which flame-retardant material is used, whether the panel and enclosure are moulded as one unit by the supplier, and whether the DIN rail and busbar set are included. LYE manufactures the LYC1 in Wenzhou and holds ISO9001, ISO14001, ISO45001, CCC, CE and TUV certification.How much does a full-plastic distribution box cost?
Indicative factory-direct pricing is roughly US$8 to US$120 per unit, depending on the way count, whether the box is supplied assembled with breakers, and the quantity ordered. Plastic enclosures are usually cheaper than stainless steel alternatives for the same duty, so the comparison that matters is against painted steel over the expected service life in a damp location.

Use a distribution box for final circuits and compact branch protection; use a cabinet when the project needs larger incoming capacity, more feeder groups, metering, busbars or greater internal separation. The final choice should be checked against the single-line diagram, device list, available installation space and local project rules.
Provide the device schedule, circuit quantity, component dimensions, cable-entry direction, mounting method and required spare capacity. LYE also reviews door clearance, bending radius, heat-producing devices and the usable depth behind the mounting plate before confirming an enclosure size.
Start with the actual exposure to dust, rain, cleaning water and accidental contact rather than choosing the highest number by default. Cable entries, ventilation, door seals and installation workmanship affect the finished assembly, so the target rating and verification basis must be confirmed for the specific product and project.
Coated or galvanized steel is commonly considered for general indoor service, stainless steel for humid or corrosive locations, and engineering plastic for lightweight non-metallic applications. Material grade, thickness, UV exposure, chemical contact and earthing requirements must be confirmed against the installation environment.
Share the component heat load, ambient temperature, solar exposure, duty cycle and allowable internal temperature. LYE can then review enclosure volume, spacing, ventilation or fan provisions, sun shields, heaters or drainage details; the final thermal design remains tied to the installed equipment and site conditions.
Yes. A dimensioned drawing is preferred, but a physical sample and clear reference photographs can also start the review. Material, thickness, openings, hardware, finish, labels, inspection points and packing are recorded before sampling or repeat production.
PDF and common 2D CAD drawings are suitable for most enclosure enquiries, while 3D files can help with complex assemblies. Include a revision number, units, tolerances and component references; file compatibility and any missing production information will be confirmed during review.
A sample or first article can be arranged for a new or customized product. The approval plan should identify dimensions, openings, fit, appearance, hardware, labels and packaging, together with the sample cost and timing agreed for the actual order.
Available documents may include approved drawings, packing lists, dimensional or appearance inspection records, product data and certificates applicable to the confirmed model. Destination-specific declarations or third-party testing must be requested before order placement so availability and scope can be verified.
Lead time is confirmed after the product scope, quantity, sample requirement and finish are known. Packing is reviewed against product weight, surface protection, destination and shipping method; if an issue is found after delivery, send the order reference, label, photographs and quantity affected so it can be traced and reviewed.
