1 DIVISION 16 BASIC MATERIALS, METHODS, AND REQUIREMENTS SECTION 16A-1 PART 1: GENERAL 1.1 SUMMARY.1 This section covers materials, methods, and requirements common to all electrical work..2 When it becomes necessary to test the emergency lighting system in a store, under no circumstances is the electricity in the building to be turned off, then on again while the registers and related electronic hardware are plugged in. If this equipment is not unplugged the resulting surge will have very damaging effects on the point-of-sale system. This holds true whether the store is using Data Terminal System or National Cash Register equipment. All the equipment must be shut down in an orderly fashion and put in an idle state prior to unplugging the electronic equipment related to the point-of-sale system. Once this is accomplished the electricity may be turned off and on as often as necessary.
