This section applies to the electrical installation of PV generator intended to supply all or part of an installation and feeding of electricity into the public grid or local distribution. In this section, the electrical equipment of a PV generator, like any other item of electrical equipment, is dealt with only so far as its selection and application in the installation is concerned. The electrical installation of a PV generator starts from a PV module or a set of PV modules connected in series with their cables, provided by the PV module manufacturer, up to the user installation or the utility supply point. Requirements of this document apply to – PV generators for supply to an installation which is not connected to a system for distribution of electricity to the public, – PV generators for supply to an installation in parallel with a system for distribution of electricity to the public, – PV generators for supply to an installation as an alternative to a system for distribution of electricity to the public, – appropriate combination of the above.

The rules of IEC 60364-4-44 are intended to provide requirements for the safety of electrical installations in the event of voltage disturbances and electromagnetic disturbances generated for different specified reasons. The rules of this IEC 60364-4-44 are not intended to apply to systems for distribution of energy to the public, or power generation and transmission for such systems (see the scope of IEC 60364-1) although such disturbances may be conducted into or between electrical installations via these supply systems. Clause 443 specifies requirements for protection of electrical installations against transient overvoltages of atmospheric origin transmitted by the supply distribution system including direct strikes to the supply system and against switching overvoltages. Clause 443 does not specify requirements for protection against transient overvoltage due to direct or nearby lightning strokes on the structure. NOTE For risk management for protection against transient overvoltage due to direct or nearby lightning strokes on the structure, see IEC 62305-2.

The particular requirements specified in this part of HD 60364 apply to onshore installations dedicated to supply inland navigation vessels for commercial and administrative purpose, berthed in ports and berths. For single- and three-phase supplies to pleasure craft, use HD 60364-7-709. This part of HD 60364 applies to installations with nominal supply voltage a.c. 400/230 V, single-phase and three-phase, 50 Hz. Additional requirements that do not relate to electrical installation are given in EN 15869-1 and EN 15869-2. The particular requirements do not apply to the onboard installations of inland navigation vessels including their connection cables. Additional requirements on the onboard installation are given in EN 15869-3.

IEC 60364-7-753:2014 applies to embedded electric heating systems for surface heating. It also applies to electric heating systems for de-icing or frost prevention or similar applications. Both indoor and outdoor systems are covered. Heating systems for industrial and commercial applications complying with relevant parts of IEC 60519, IEC 62395 and IEC 60079 are not covered. This second edition cancels and replaces the first edition published in 2005 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - 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.
