Section 124. Except as otherwise provided in this chapter, a gas or electric company may stop gas or electricity from entering the premises of any person failing to pay the amount due therefor or for the use of the meter or instrument necessary to measure supply of service; and for such purpose, the officers, servants or workmen thereof may, after three days’ notice by mail, exclusive of Saturdays, Sundays and legal holidays, enter his premises between the hours of eight in the forenoon and four in the afternoon and separate and take away such meter or other property of the company, and may disconnect any meter, pipe, wires, fittings or other works, whether they are property of the company or not, from its mains, pipes or wires. In the event a person is being serviced by gas or electricity at two or more premises at the same time, a gas or electric company may enter only those premises to which the unpaid amount relates.
