Описание
IEC 60364-7-721:2017(E) lays down particular requirements applying to electrical circuits and equipment intended for the use of the caravan for habitation purposes. This new edition includes the following significant technical changes with respect to the previous edition:
- a minimum height of not less than 500 mm above the base of the cylinders is now required for cables passing through the gas cylinder compartment;
- it is now required that each independent installation shall be provided with its own main isolating switch which shall disconnect all live conductors and which shall be suitably placed in a readily accessible location in the caravan.
