The provisional facilities are those that have a limited duration due to their circumstances. They are provided for in Royal Decree 842/2002, of August 2, which approves the low voltage electrotechnical regulation. They may be:
Repair. Those necessary to alleviate an exploitation incident.
Work. Those made to allow changes or transformations of the facilities, without interrupting the operation.
Semi-permanent. Those destined to modifications of limited duration, within the framework of habitual activities of the premises in which they are repeated periodically (Fairs).
Of works. They are intended for the execution of construction work for buildings and the like.
If you want to make a construction from scratch, or some major reform and want to hire electricity only to carry out the construction, it is not necessary that you hire a common Light Rate but that the Distributor Companies have a special type of new installation for these cases.
