Hostel Wiring Circuit Diagram and Its Operation
Hostel wiring circuit is especially designed and used for study hours by headmasters and wardens to transport 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. The rooms lights also controlled through SPDT (single pole double throw or two way switches). All these switches and light bulbs in the rooms are configured in such an arrangement where the light of the rooms can be controlled dependently through SPDT switches and independently through master switch during the study hours specified by the management and wardens.
In the hostel lighting circuit, lighting bulbs can’t be turned off during the study hours. For example, the room lamps can be switched ON and OFF directly by switching the 2 way switches in the student rooms. On the other hand during the study hours, warden switch ON the master switch so that, the students won’t be able to turn OFF the light bulbs. When the study hours period ends, warden again switch OFF the master switch, hence the student will be able to turn OFF the lighting points.
Procedure:
First of all, turn off the main breaker to ensure the main supply is switched OFF.
Connect all the switches to the grounding / grounding terminals (not shown in the fig)
Connect the Neutral wire from MCB directly to all the three lamps as shown in fig.
Connect the Line (Phase or Live) wire to the first terminal of SPST switch and lower terminals of all SPDT switches.
Connect an auxiliary wire to the first SPST switch upper terminal and all SPDT terminal as shown.
Connect all the light bulbs to the middle (common terminals) of SPDT (2 way) switches.
Keep in mind that you may use many switches and lamps according to your needs while following the above hostel wiring schematic diagram. as the rating of SPDT switches are the same but all the loads are operational at once where all load is carried by master switch during study hours, therefore use higher voltage and ampere for the master switch with appropriate wire size and proper size MCB according to the load rating.
