Carry on, but not smallest amount, the engineer ought to aid the client to "design in" protection competentemployees. Personnel and facilities can survive rare by incompetent jobholders.
Fire Insurance Requirements and Costs
Sanction of electrical design and installation is requisite to acceptance on behalf of fire insurance coverage.
