Distribution Boxes, Meter Boxes and Site Power Boxes for Buildings and Construction

For building lighting circuits, small power distribution, metering, and construction sites, we supply XM-series distribution boxes (surface-mount, flush-mount, or outdoor), meter boxes in galvanized steel or stainless, and standardized temporary-power boxes for site safety compliance. The same family covers a small retail unit's consumer board and a contractor's site distribution point - so one supplier can quote the whole job.

Quick Answer: Which Distribution Box Do You Need?

Decide four things and the box model picks itself: circuit count and rating (single-phase 220 V or three-phase 380 V), mounting (surface, flush or outdoor), material (powder-coated steel or stainless), and environment (dry indoor, damp, or outdoor with rain exposure). XM-1 and XM-2 cover most building and light-commercial boards; XM-3 extends the range for grouped metering or small control layouts; meter boxes (JY-BXG series) and construction-site boxes are separate product lines in the same family.

XM-Series Distribution and Control Boxes - Sizes and Mounting

The XM series covers wall-mounted distribution and control boxes from 400 mm to 1000 mm wide. XM-1 boxes (650-800 mm wide) suit building lighting and small power circuits; XM-2 boxes (400-1000 mm wide) cover distribution and control duty; XM-3 boxes (550-1000 mm wide) extend the range for grouped metering or small control layouts. All are formed from steel sheet with epoxy powder coating for corrosion resistance, and indoor or outdoor versions are available - outdoor boxes carry a sealed door with rubber gasket.

Finish, Doors and Fitting

Surfaces are finished with epoxy resin electrostatic spraying (powder coating) so the box keeps its appearance in humid or coastal interiors. Boxes can be supplied with metal doors or glazed (window) doors for reading meters and indicators without opening; outdoor and protective boxes use sealed doors with rubber sealing strips to keep out water. Internal mounting plates and cable knockouts are arranged for standard components; multimedia boxes add standard mounting rails and covered terminals.

Meter Boxes and Multimedia / Home Boxes

JY-BXG (DXB)-JLBX Meter Boxes - Galvanized or Stainless

Meter boxes in the JY-BXG (DXB)-JLBX series are produced in galvanized steel or stainless versions for grouped metering installations - utility metering boards, apartment risers and small commercial submetering. Choose galvanized for standard indoor meter rooms and stainless where the board sits outdoors, in washdown areas or near the coast.

Multimedia and Consumer-Unit Boxes

For residential and light-commercial cabling, multimedia and consumer-unit boxes combine an ABS flame-retardant front panel with a cold-rolled steel, powder-coated base, standard mounting rails and covered terminals. The range includes consumer distribution boxes (A-604/A-709 sizes), multimedia information boxes, and video/voice/network module boxes with adjustable mounting racks for video, voice and network modules in apartments and offices.

Construction-Site Temporary Power Boxes

Site power safety starts at the distribution box. Our temporary-power range covers fixed and mobile distribution boxes plus switch boxes, standardized for construction-site temporary electricity practice (JGJ 46), with the circuit diagram fixed inside the door, protected cable entries, and angle-bracket or stand mounting so the responsible electrician can identify and isolate circuits quickly. Boxes are fitted with clearly labelled incomer, outgoing and PE positions and space for the standard site labels (duty holder, contact, box number) required by site inspection.

Typical specs: 220 V single-phase / 380 V three-phase, 50 Hz; indoor/outdoor versions; sealed door with rubber gasket for outdoor; epoxy powder-coated steel, stainless option for meter boxes; temporary-power boxes with circuit diagrams, PVC-protected cable entries, and angle-bracket mounting.

Choose the Right Box: Four Inputs for a Correct Quote

1. Circuit count and rating: how many circuits, and what load per circuit? Single-phase 220 V boards for lighting and sockets; three-phase 380 V for small power, air-conditioning or site distribution.

2. Mounting and location: surface-mount or flush-mount indoors, or outdoor wall/pole installation where the box sees weather - outdoor duty adds the sealed-door version.

3. Material: epoxy powder-coated steel for standard duty; stainless for meter boxes and coastal or washdown locations.

4. Metering and special needs: does the board hold a utility meter, submeter, multimedia modules, or must it comply with site temporary-power rules (JGJ 46)? Tell us and we will configure the correct box type.

Key Details to Check Before Buying

Material and Finish

Steel boxes should be powder-coated after forming (epoxy resin electrostatic spraying) so edges and cut-outs stay protected. Stainless versions are for aggressive environments. Ask which thickness is used for the base and door - it determines rigidity when drilled on site.

Door Seal and Ventilation

Outdoor duty requires a sealed door with a rubber gasket; some designs add a drip-protected lower entry with covered glands. If the box contains heat sources (transformers, chargers), tell us - we can supply a vented or larger version instead of guessing.

Mounting and Cable Entry

Check whether the box is surface (wall), flush (recessed) or outdoor class, and where cables enter - top, bottom or rear. Flush versions need the correct recess depth; site boxes are usually delivered with angle-bracket or stand mounting and PVC-sleeved entries.

Quality, Testing and Factory Evidence

Boxes look simple, which is exactly why inspection discipline matters. The factory runs an ISO 9001-certified quality management system with three inspection gates: incoming checks on steel sheet, coating materials and components; in-process inspection during cutting, forming and coating; and outgoing inspection of finished boxes before packing. Where boxes are supplied factory-fitted with devices, the assembled board also receives insulation and function checks before dispatch.

The same inspection line serves the whole box family - insulation-resistance and withstand test equipment for fitted assemblies alongside dimensional and coating checks for enclosures. Routine inspection records are available on request with your order.

Where These Boxes Are Used

The range covers three buyer groups. Electrical contractors and building owners use XM-1/XM-2 boards and consumer-unit boxes for lighting, socket, air-conditioning and small power circuits in apartments, villas, offices, shops, schools and hotels. Utilities and property managers use JY-BXG meter boxes and XM-3 grouped boards for metering risers and distribution cupboards. Construction companies and site electrical supervisors use the temporary-power line for site distribution, meeting the fixed/mobile distribution and switch-box layout required by Chinese site safety practice (JGJ 46) and familiar to contractors running disciplined site power on any project.

Frequently Asked Questions

1. What is the difference between XM-1, XM-2 and XM-3 boxes?

XM-1 (650-800 mm wide) is the lighting and small-power board for buildings; XM-2 (400-1000 mm wide) covers distribution and control duty with more layout options; XM-3 (550-1000 mm wide) extends the range for grouped metering or small control arrangements. Width series are the practical difference - choose by circuit count and device space.

2. Do I need stainless steel or galvanized steel for meter boxes?

Galvanized steel covers standard indoor meter rooms. Choose stainless when the meter box is outdoors, in washdown areas, coastal sites or industrial atmospheres where rust matters more than the small cost difference.

3. Can boxes be made with a window door for meter reading?

Yes - glazed (window) doors are available so meters and indicators can be read without opening the box. State the cut-out position and the meter brand/dimensions so the window aligns with the display.

4. Are the site temporary-power boxes built to a standard?

They are standardized for construction-site temporary electricity practice (JGJ 46): fixed and mobile distribution boxes and switch boxes with the circuit diagram inside the door, protected entries and standard mounting. If your project follows a different site-electricity code, send the clause list and we will confirm what changes are needed.

5. Can I get a box without any internal devices (empty enclosure)?

Yes - boxes are supplied empty with mounting plates and rails, or factory-fitted with breakers and terminals per your schematic. Empty enclosures are the fastest option for local fitters; fitted boxes save site labour. Say which you need when asking for a quote.

6. What standards are these boxes designed to?

The boxes are designed to the IEC 60439-1 and GB 7251 series requirements for low-voltage switchgear assemblies. If your project needs specific certification or a third-party inspection, include it in the enquiry and we will confirm scope before quoting.

7. Can I get inspection or test records with my order?

Yes - routine inspection records from the factory's outgoing check are available on request. For project requirements such as witness testing or third-party inspection, tell us when enquiring so it is planned into production and delivery.
