What is tunnel circuit?
What is tunnel circuit?
Tunnel wiring circuit is used in open ended corridors and short tunnels like structures. In tunnel wring circuit diagram, we have used SPDT (two-way) switches to control the lighting points in tunnels and corridors. The tunnel circuit control the lamps in four ways as follow.
What is tunnel lighting?
Tunnel lighting is necessary to solve the problem of abrupt adaptability of the environment inside the tunnel. It is necessary to balance the adaptability of the inside and outside luminance for the person entering or exiting the tunnel. This design is based on certain critical length of the tunnel.
How many switches are required for godown wiring?
3 Comments. circuit Diagram of godown wiring is good. the diagram they use 2 pics switches 2gang. And 1 switch is 1gang.
What is godown wiring?
Godown wiring uses to operate lamps/loads in a sequential manner, where only one load operates at a time. The advantage of the godown wiring is the previous load will be turned off when we normally switch ON the next load. In godown wiring, the loads are not controlled by a random switching.

What are the 5 zones of tunnel lighting?
Tunnel lighting is divided into five zones according to different design brightness: access zone lighting, threshold zone lighting, transition zone lighting, interior zone lighting, exit zone lighting.
Which tunneling light is best?
Counter-beam or symmetrical/asymmetrical lighting point source luminaires like Philips TubePoint models will be the most appropriate light sources for a tunnel entrance zone.
What is hostel wiring?
Hostel wiring circuit is especially designed and used for study hours by headmasters and wardens to convey the students to do their study instead of early sleeping. In hostel wiring circuit, there is a SPST (single pole single throw or one way or single way) switch installed as a master switch in the warden room.
Which is the most type of wiring used in domestic applications?
Explanation: The most common type of wiring in modern homes is in the form of nonmetallic (NM) cable, which consists of two or more individual wires wrapped inside protective plastic sheathing.
What are different types of wiring?
Types of Wires – There are several essential types of wire that one must know for understanding their place of usage.
- Triplex wires.
- Main feeder wires.
- Panel feed wires.
- Non-metallic sheathed wires.
- Single strand wires.
