A1 Gopala Krishnan,Former AssistantGeneral Manager 1996-2004 at Department of Telecom (1966–2004)2m I am answering fromChennai, India. In modern wiring for future expansion in concealed wiring a puller wire is provided inswitch boxes and spare switches one or two are provided. Theswitches will remain without any connection. When additional light, fan etc.are to be provided these switches are provided. Similarly UPS wiring may also be available in many switchboxes, end insulated and kept. This is for providingUPS supply to additional equipment if necessary. Recently to myinterest I found in the switch box in the bottom of staircase a calling bell tocall persons in the first floor, a DC switch. The bell was not working. When the electrician cameand opened the switch box, he found the switch, having no AC power supplyextended, but wired. He replaced the battery in the bell, and found the callingbell functioning perfectly. Immediately I marked the switch as DC switch. Actually DC has to be wired separately. Probably the builder intended it can bemade an AC switch, extending power supply and providing an AC bell whenrequired. Q2 How long can I leave a circuit breakerturned off?
