Stage 1 — rough
Before plastering: chasing, cable laying, boxes, panel, grounding. Result: walls ready for plastering, wires in the boxes.
Stage 2 — finishing
After the finish: sockets, switches, lights, panel assembly, testing. Result: working electrical system.
When the panel is installed
Rough stage — the panel body with the input; the devices — at the finish, after the walls are clean.
What to do in advance
The project with the socket positions — BEFORE the chasing. Materials — per the specification, before the rough stage.
Typical mistakes
Chasing without a project — rework; plastered sockets at the wrong height; no project for the inspector — redone in a month.
Why a project first
The project fixes the sockets before the walls close. Changing a socket after the wallpaper is 100 times more expensive.
