Switchgear / MCC line-up

Line-up of MV metal-clad switchgear, LV switchboard or motor control centre panels. MV panels carry a protection relay, ammeter, indicator lamps, breaker viewing window, racking point, earthing-switch socket and bolted cable compartment under an arc-gas duct, with bolted rear covers for rear access; LV / MCC sections have withdrawable tiers with rotary isolators. Panel size follows the type and voltage; the plinth adds a rear cable trench, rubber operator mat and main earth bar.

Installation

Copies electrical/switchgear.tsx and the shared lib/ into src/components/deck-twin/. Needs three, @react-three/fiber and @react-three/drei. See installation for the manual route.

Usage

import { Canvas } from '@react-three/fiber'
import { OrbitControls } from '@react-three/drei'
import { Stage } from './components/deck-twin/lib/stage'
import { Switchgear } from './components/deck-twin/electrical/switchgear'

export default function Scene() {
  return (
    <Canvas shadows camera={{ position: [8, 5, 9], fov: 35 }}>
      <Stage>
        <Switchgear />
      </Stage>
      <OrbitControls makeDefault />
    </Canvas>
  )
}

Props

P&ID

Thick horizontal busbar with an incoming feeder and several outgoing feeders, each through a circuit breaker (a switch blade with a small × on the fixed contact) or contactor, often inside a dashed boundary with the board tag and voltage.

tag SWGtag MCCIEC 60617 (single-line diagram)

Breaker: × on the contact. Disconnector: a bar across the contact. Contactor (MCC starter): a half-circle on the contact. On layouts a switchgear line-up is a long rectangle divided into panels inside an E-house.

For agents

Machine-readable entry with props, ranges, defaults and ports:

Or fetch /r/switchgear.json, or copy a ready-made instruction:

Add the Deck Twin "Switchgear / MCC line-up" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add switchgear` (it copies the file and the shared lib into src/components/deck-twin/), then `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz info switchgear` for its props, ranges and ports. Render <Switchgear /> inside a React Three Fiber <Canvas shadows>, wrapped in <Stage> from src/components/deck-twin/lib/stage. Set props from my data (metres, NPS in inches, ASME class) and leave the rest at defaults. Install three, @react-three/fiber, @react-three/drei and @types/three if they're missing.
