Upon completion of an electrical installation, which has been authorized
by permit, the electrical contractor shall notify the Building Inspector,
who shall inspect the installation promptly. If it is found to be fully in
compliance with the provisions of this chapter, said Building Inspector shall
issue a certificate of approval, or may endorse his approval upon the certificate
of approval issued by a certified electrical inspector for the same work.
Such certificates, when so issued, or when so endorsed, shall be delivered
to the electrical contractor to whom permit for the work was issued, and shall
constitute authorization for connection to the electric service and the use
of the installation.
A certificate may be issued authorizing the connection and use of temporary
work for a stated time, and a preliminary certificate may be issued authorizing
the connection and use of certain specified portions of an uncompleted installation.
Both such certificates shall be revocable at the discretion of the Building
Inspector.
When any part of an installation is to be concealed by the permanent
placement of parts of the buildings, the electrical contractor shall notify
the Building Inspector, in writing, and such parts of the installation shall
not be concealed until they have been inspected, or until 48 hours, exclusive
of Sundays and legal holidays, have elapsed from the receipt of such notification
by the Building Inspector, provided that on large installations where the
concealment of parts of the installation proceeds continuously, the Building
Inspector may, in his discretion, authorize the electrical contractor to give
the uilding Inspector due notice and inspections shall be made periodically
upon a schedule for such installation.
