Conversion is an interface project
Replacing or converting switchgear affects dimensions, bus and cable connections, protection, isolation, fault duty, controls, and maintenance. The existing assembly and the proposed equipment must be compared as a system, not only by nominal current.
Inputs to collect
| Input | Why it matters |
|---|---|
| Existing drawings and nameplates | Establishes the as-found configuration |
| Bus, cable, and mechanical dimensions | Determines fit, termination, and modification work |
| Protection and fault data | Confirms device duty and coordination changes |
| Outage and temporary supply plan | Defines operational and safety constraints |
| Control and metering interfaces | Preserves trips, alarms, interlocks, and records |
| Testing and handover evidence | Documents inspection, verification, and responsibility |
Scope boundary
This is a planning checklist, not a conversion method or live-work instruction. A qualified electrical engineer must approve the design, outage, isolation, testing, and final energization plan.
