Low-voltage electrical installations - Part 7-753: Requirements for special installations or locations - Heating cables and embedded heating systems
- the title has been changed from "Floor and ceiling heating systems" to "Heating cables and embedded heating systems" to align with the revised scope;
- the scope has been extended and now covers embedded electric heating systems for surface heating, also electric heating systems for de-icing or frost prevention or similar applications, and covers both indoor and outdoor systems. This includes heating systems for: walls, ceiling, floors, roofs, drainpipes, gutters, pipes, stairs, roadways, non-hardened compacted areas (e.g. football fields, lawns);
- for wall heating systems, this standard contains additional requirements (e.g. metal sheath/enclosure/grid) to protect against the effects of overheating caused by a short-circuit between live conductors due to penetration of an embedded heating unit;
- from heating units delivered from the manufacturer without exposed-conductive-parts, this standard requires a metallic mesh grid covering. This has been reduced to 3 mm for wall heating systems;
- this standard now requires that electric heating systems shall be selected and erected so as to avoid any harmful influence between the heating system and any electrical or non-electrical installations envisaged;
- and this standard covers surface temperatures and now refers the reader to the appropriate IEC guide.
