Distribute agreed circuits through a suitable DB or sub-DB with documented protection and labels. Supply capacity, circuit loading, fault requirements, earthing, spare ways and safe maintenance access shape the final assembly.
Conceptual DB Board / Distribution Board / Sub-DB product and system illustration for Electrical. Final device form, model, interfaces and quantities are confirmed from the assessed scope and approved product data. Conceptual supply, protect and verify path for DB Board / Distribution Board / Sub-DB, derived from this page's scope, interfaces and acceptance record.
Conceptual planning path — not an as-built drawing or project photograph.
Distribute agreed circuits through a suitable DB or sub-DB with documented protection and labels. Supply capacity, circuit loading, fault requirements, earthing, spare ways and safe maintenance access shape the final assembly.
It sits in LV Electrical under Electrical. The final deliverable is shaped by the intended outcome, the installed or proposed environment and the interfaces that must be owned, supplied, integrated and tested.
Distribute agreed circuits through a suitable DB or sub-DB with documented protection and labels. Supply capacity, circuit loading, fault requirements, earthing, spare ways and safe maintenance access shape the final assembly. Prepare the supply and circuit schedule, load requirements, existing protection, fault information, earthing arrangement, space, spare ways, safe isolation access and required drawings and tests.
From the initial brief to the handover record: what to prepare, check and confirm with HJ.
Define Electrical as the operating result for DB Board / Distribution Board / Sub-DB, including the users, process and exceptions it must serve.
Distribute agreed circuits through a suitable DB or sub-DB with documented protection and labels. Supply capacity, circuit loading, fault requirements, earthing, spare ways and safe maintenance access shape the final assembly.
For DB Board / Distribution Board / Sub-DB, confirm load and diversity schedule, source, DB capacity and fault conditions, route, protection, earthing and competent-person boundary.
Prepare the supply and circuit schedule, load requirements, existing protection, fault information, earthing arrangement, space, spare ways, safe isolation access and required drawings and tests.
Map Supply or source → Isolation & protection → Distribution or containment → Load & test record for DB Board / Distribution Board / Sub-DB and identify every interface owned by HJ, the customer, ISD supply or an appointed specialist.
Design, isolation, testing and energisation require applicable competent or appointed persons; ELV interfaces do not transfer electrical responsibility. Final models, capacities and quantities still follow survey, compatibility and availability.
Electrical work requires qualified responsibility, an agreed design, safe access and applicable approvals. Protection functions are not interchangeable, and a visual inspection does not prove circuit compliance.
For DB Board / Distribution Board / Sub-DB, record inspection and circuit identification, applicable continuity, insulation, polarity and earth tests, protection, load, SLD and signed records; also agree protection and isolation checks, load or functional test, label, drawing and responsible-person record before handover.
Retain the circuit schedule, qualified inspection and agreed test results, device identity and settings, exceptions and authorisation before energisation or return to service.
HJ coordinates assessment, engineering, installation, integration, testing and lifecycle support only for the scope recorded in the quotation. ISD handles catalogue, model, datasheet, supply and availability enquiries. Customer, consultant, builder and appointed-specialist responsibilities remain explicit.
Regulated or multi-discipline work proceeds only after site assessment and confirmation of the competent, qualified or appointed persons, approvals, safe isolation and responsibility required for that scope.
This focused topic remains connected to its complete system owner. Final models, quantities, interfaces and included work are confirmed in the assessed quotation.

Use the answers as a planning boundary; site conditions and written scope remain decisive.
