Cable capacity and CEI 64-8 compliance

According to CEI 64-8, to ensure that cables can be withdrawn from the conduit, the maximum cable diameter depends on the length of the run:

• For runs up to 10 m, the maximum cable diameter is 10 mm.
• For runs up to 20 m, the maximum cable diameter must not exceed 9 mm.

Installation and mounting recommendations

The tube is intended for surface-mounted installations on walls or ceilings, in new builds or refurbishments. It can be fixed using clips, saddles, staples or dedicated accessories for decorative exposed conduits.

Due to the shape of the tube, once installed it may be necessary to cut off any protruding wire sections before fitting accessories or inserting the tube into junction boxes. This ensures a neat finish around lampholders, sockets and other surface-mounted components.
