(4) Temporary installations. Modifying or waiving certain of the rules will sometimes be necessary in case of temporary installations or installations which are shortly to be dismantled or reconstructed. Such temporary construction may be used for a reasonable length of time without fully complying with this code, provided it is under competent supervision while it or adjoining equipment is energized or if it is protected by suitable barriers or warning signs when accessible to any person; but all such construction shall be made reasonably safe.
