Box Build Assemblies Prato: Box build assemblies take electrical and electromechanical parts into an enclosure, wire them, label them and deliver the unit ready to install: a control box, a power cabinet or an equipment housing. The customer provides the schematic and the bill of materials; a manufacturer selected from the network builds the unit. Justicia Marin is a technical distributor and supplier that coordinates the order and has no workshop of its own. For companies in Prato, Justicia Marin records the drawing, materials and quantities, checks the right manufacturer in its network and coordinates the supply. The box build and the wiring is done by the selected manufacturer; the customer approves the specification and the acceptance criteria.
From schematic to wired enclosure
Box build means assembling the enclosure, mounting components, routing and terminating the wiring, marking it and testing the unit as agreed. Control panel wiring and electrical cabinet wiring are the same work focused on panels and cabinets. The result is a self-contained unit that the customer mounts and connects on site or in the final equipment. This page covers box build, control panel and cabinet wiring as a supply service: from schematic, layout and bill of materials to quotation, first unit and repeat orders. Individual cable assemblies and wire harnesses have their own pages. Justicia Marin does not manufacture; it selects a manufacturer for the unit, compares offers and coordinates delivery. Panel and enclosure work depends on the customer’s schematic, layout and applicable rules. It is not assumed that every manufacturer works to every standard or panel type.
Layout, wiring rules and tests
A box build quotation is comparable only when the layout, the wiring rules and the tests are described in the same way for each manufacturer. The following four decisions should be settled before the request, so that part, price and inspection describe the same result.
The schematic and the mounting layout fix component positions, wire routes and terminal assignments. Open points are raised before quotation, and changes after release restart the comparison.
Components, terminals, enclosures and accessories are listed by part number. Free-issue parts are counted and checked on arrival; sourced parts follow approved references.
Wire types, colours, ferrules, cable duct and the marking scheme are specified. Every circuit is identifiable at both ends as the schematic requires.
Continuity, insulation or functional tests and the limits that apply are agreed in advance. The manufacturer documents the results and supplies the records with the unit.
Details for the quotation
A panel or box build can be quoted when schematic, layout and bill of materials are complete. Missing items are raised before the request goes out. If a dimension or a criterion is missing, we point it out before the request goes to the manufacturer. We do not replace the customer’s documents with assumptions that have not been approved.
Projects in Prato
Prato is a city in Tuscany, Italy. Industrial activity in and around the city includes machine building, technical textiles and industrial automation, which creates demand from machine builders, textile-machinery makers and automation integrators. Context: Tuscany (Italy). Bologna is about 70 km to the north of Prato, and Florence about 18 km to the south-east. Prato has a population of about 195,000 (2023). Prato is part of the Province of Prato. Machine building is a visible part of the industry around Prato; machine-wiring requests there are usually repeatable variants that follow the machine range. If the request comes from a company in the “machine building” sector in Prato, the following applies: the schematic and the layout define the unit, not the delivery address. The presence of an industry in the area does not mean that Justicia Marin has a site, production or customers there. The manufacturer is selected for demonstrated capability against the specification, not for proximity. Regional reference: Comune di Prato.
The schematic and layout with their revision are the reference for quotation, first unit and series. Where they are incomplete, open points are listed before pricing.
Every component is identified by part number and checked on arrival, so the unit is built from approved references only.
The manufacturer carries out the agreed tests and documents them. Justicia Marin coordinates the records; the assessment in the final installation stays with the customer.
From specification to series
We clarify schematic, layout and parts with the customer, consult manufacturers about capability, and coordinate first unit, quotation and supply.
Receive the documents
The customer sends schematic, layout, bill of materials and acceptance criteria.
Select the manufacturer
Justicia Marin reviews the documents, lists open points and asks suitable manufacturers to confirm capability and price.
Approve the first unit
A first unit is built and checked by the customer before the quantity is committed.
Supply and repeat
The manufacturer builds the units to the approved configuration; Justicia Marin coordinates documents, delivery and repeat orders.
Responsibilities
Justicia Marin is a technical distributor and coordinates the supply; it is not the workshop that carries out the box build and the wiring. We receive the documents, consult the right manufacturer and coordinate first unit, quotation and supply. The selected manufacturer works and documents the agreed inspections; the customer remains the owner of the drawing and accepts the result.
Defines schematic, layout, components, marking and tests; approves alternatives and the first unit; validates the unit in the final installation.
Analysis — schematic, parts and open points
Selection — manufacturer and offer comparison
Start — first unit and release
Delivery — documents, revisions and delivery
The selected manufacturer mounts and wires the unit to the schematic, marks the circuits, carries out the agreed tests, documents the results and reports before the start if a part or document does not match.
Justicia Marin coordinates the supply. It has no workshop, production line or laboratory of its own and does not issue certificates. Assembly, wiring and the agreed tests are carried out by the selected manufacturer; the design and the final validation stay with the customer.
