Electrical · power, lighting & low current

The electrical installation,
from the board to the schematic.

Place switchboards, luminaires, sockets and detectors, chain them with cables, route the cables onto trays with their supports, check loads, voltage drop and short circuit — then draw the board's single-line schematic and the control pages from the same model.

The complete building from the north-east in realistic 3D with the VM Electrical tab: luminaires, cable trays and cables of both floors with the ductwork and pipes — Luminaires, trays and cables of both floors in the complete building — VM Electrical tab

Cables that know their circuit

Each cable chains its devices back to the board; circuits, loads and protections are kept per board and checked with VMCIRCUITS.

Cable routes in 3D

Trays, ladders, trunking and conduit with fittings and supports; cables routed onto them, packets to the board and the tray fill checked.

Schematics from the model

Single-line schematics of the boards and Circuit Designer control pages with cross references, terminals and device lists.

Plan and 3D

Luminaires in every room, sockets along the walls, the corridor trays and the cables of each circuit to the switchboards — in plan with their symbols, and in 3D.

Ground-floor electrical plan: luminaires, sockets, cables and circuits along the corridor to the switchboards — The ground floor's electrical plan

First-floor electrical installation in realistic 3D: luminaires, the cable tray along the corridor and the cables to every device — The first floor in 3D: luminaires, tray and cables

The electrical room and the trays

The main switchboard, the data rack and the fire alarm panel; the trays leaving the room along the corridor with their supports, and the cable packets up to the boards.

Schematics and control pages

VMSCHEMA draws the switchboard's single-line schematic from its circuits; the Circuit Designer draws the air-handling unit's motor starter with its contactor, overload relay and push buttons, cross-referenced and numbered.
