Full-Plastic Surface-Mounted Distribution Box: Key Features & Typical Use
No Cavity, No Chasing
The LYC4 mounts directly onto a wall, a post or the side of a piece of equipment, so a circuit can be added outdoors without cutting a recess into a finished surface. That makes it the practical option for retrofit work on a site where chasing a wall is not acceptable, and for mounting on posts where no wall exists at all.Plastic Housing Where Metal Would Suffer
Both the panel and the enclosure are ABS flame-retardant material, so the housing resists corrosion in damp, coastal and chemically exposed positions. On a farm or a parking area, an enclosure that is mounted externally and receives no maintenance is exactly where a plastic body outperforms a coated steel one.4 to 20 Ways for Small Outdoor Circuits
The range covers 4 ways to 20 ways, from LYC4-4 at 135 x 155 x 88 mm up to LYC4-20 at 455 x 215 x 88 mm, all at 88 mm depth so the projection off the mounting surface is consistent. That suits the circuit counts found in parking areas, breeding farms and temporary outdoor power points.Check the Breakers Without Disassembly
A PC observation window with a flip-top design lets breaker positions be verified without removing the cover, so a tripped outdoor circuit can be found quickly and the enclosure is not opened unnecessarily. Each unit ships with the panel, the neutral and earth busbar set, a DIN rail and the enclosure, and takes standard breakers.Full-Plastic Surface-Mounted Distribution Box Specifications & Technical Data

LYC4 — Surface-Mounted Outdoor Distribution Box
Not every outdoor circuit can wait for a recess. The LYC4 mounts straight onto a wall, a post or the side of a piece of equipment, so power can be added to a parking area, a farm building or a temporary site position without cutting into a finished surface or waiting for masonry work.This box is also called a surface-mounted outdoor breaker box, a wall-mount distribution box or a post-mounted electrical enclosure, and it is compared with recessed plastic boxes and with metal outdoor cabinets. It is chosen when there is nothing to recess into: it mounts on a finished wall without chasing, on a post where no wall exists, or onto the side of a piece of equipment.The housing is full plastic — an ABS flame-retardant panel and enclosure with a PC observation window — so it resists corrosion in damp, coastal and chemically exposed positions where a coated steel box mounted externally and rarely inspected would fail. A flip-top window lets breaker positions be checked without removing the cover.Five models cover 4 ways to 20 ways, from LYC4-4 at 135 x 155 x 88 mm up to LYC4-20 at 455 x 215 x 88 mm, all at 88 mm depth so the projection off the mounting surface stays consistent. Each box is supplied with the panel, the neutral and earth busbar set, a DIN rail and the enclosure, and takes standard circuit breakers.Factory-Direct Full-Plastic Surface-Mounted 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 LYC4 Full-Plastic Surface-Mounted 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 LYC4 we mould the flame-retardant body and cover in our own works, so the cable entry positions and mounting points can be set for how the box will actually be fixed.- 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.

What is a surface-mounted distribution box?
It is a distribution enclosure that fixes onto a finished surface rather than being recessed into it, so no cutting or chasing is required. The LYC4 is a full-plastic surface-mounted box with an ABS flame-retardant panel and enclosure and a PC observation window, covering 4 to 20 ways at a consistent 88 mm depth, for walls, posts and equipment mounting.When is a surface-mounted box the right choice?
Whenever a recess is impossible or undesirable: retrofit work on finished walls, mounting on posts or structural steel where there is no wall, equipment-mounted positions, and temporary or semi-permanent outdoor supplies where cutting masonry would be disproportionate to the job. It is also used where cables have to reach the box from above and a flush fixing would be awkward.Is a plastic box suitable for outdoor installation?
Yes, provided the moulding and the sealing are designed for it. The LYC4 uses an ABS flame-retardant panel and enclosure with a PC observation window, so it resists corrosion in damp, coastal and chemically exposed positions where a coated steel box mounted externally and rarely inspected would deteriorate. Cable entries still have to be sealed with suitable glands to keep the enclosure rating.Who manufactures surface-mounted distribution boxes?
The category includes specialist moulded-enclosure factories and general electrical manufacturers, so the variables are the flame-retardant grade, the sealing design and the internal arrangement. Ask whether the housing is moulded by the supplier, how the observation window is fitted, and whether the DIN rail and busbar set are supplied. LYE manufactures the LYC4 in Wenzhou and holds ISO9001, ISO14001, ISO45001, CCC, CE and TUV certification.How much does a surface-mounted distribution box cost?
Indicative factory-direct pricing is roughly US$8 to US$120 per unit, depending on the size, the way count, whether breakers are fitted and the quantity ordered. Because the range steps from 4 to 20 ways at a constant depth, mixed sizes can be supplied for a single site in one shipment, which keeps both the unit cost and the spares holding down.

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.
