The exact measurement is known only by the project, but you can estimate the volume of the purchase in a minute. Wiring is usually divided into two groups: sockets - with a cable 3x2.5, lighting - 3x1.5. Then we calculate based on the number of points and the average length of the line from the distribution board, with a margin for turns and connections.
The estimate has a margin of about 15%. Points on the same line are usually rounded up, so the actual consumption is often lower — the figure is needed to avoid buying exactly enough.
| Housing | Cable consumption (sockets + lighting), m |
|---|---|
| Studio apartment | 80–120 |
| 2-bedroom apartment | 120–180 |
| 3-room apartment | 180–250 |
| Private house | From 300. |
