KIT – KAT TYPE FUSES

Kit – Kat Type Fuses are a type of Low Voltage (LV) Fuses. Kit Kat Fuse is a semi-enclosed fuse also considered as rewireable fuse designed mainly for the domestic wiring and small scale usage.

The main composition of this fuse is Porcelain base which holds the wires together. Fuse element is located under the carrier that is also made up of porcelain material.

The fuse carriers that contain a length of fuse wire, which is wrapped around the terminals, covering the space between carriers and pins, to complete the circuit. It is used in interrupting the circuit in conditions like over-current or short-circuits.

They are most commonly used in house wiring, small industries and other small current applications.

The fuse is wired in series with the circuit to be protected. During the fault, the circuit current rises in value. Therefore, the heat produced at the fuse causes temperature of the fuse wire to rise to a value high enough to melt the wire and thus break the circuit.

It requires minimum time to replace. It has current limiting effect. It is the cheapest form of fuse.

Kit-Kat fuse cannot be used for higher values of fault current. Protection is not reliable due to inaccurate characteristics. Also there is always a risk of fire hazards. For such installations use of MCB & RCCB is suggested.

Extension Cord Vs Power Strips Vs Spike Guards

Extension Cord An extension cord is used to connect an electrical cord to the outlet if the main cable falls short. T heir job is to extend the reach of a wall receptacle. Extension cords vary in length and type of outlet plug. They can be anywhere in length from two feet to as long as one hundred feet. The longer the extension cord, the bigger the drop in amps. It’s important to use a cord which is a rated enough for the tool or appliance. A under rated cord will experience overload causing overtemperture which is dangerous and this makes it are among the most dangerous electrical devices in our homes. So we should not use it as a permanent electrical connection. Connecting two extension cords together should be avoided as it creates a drop in amperage also too long extension cord can create a tripping hazard. Power Strips A power strip is a device that has an electrical plug, a series of sockets, and a cable. The cable plugs into an outlet in your wall, and then the strip ...

Two Way Switch

Image
A Switch is an electrical device which is used to open or close an electric circuit. There are different types of switches: Toggle Switch, Momentary Switch, Rocker Switch, Digital Switch, etc. All the switches perform simple task of ‘make’ or ‘break’ the circuit. Normal switch has two states - ON/OFF. All the switches we use regularly to turn on or off lights, fans, etc. are two terminal devices.  But there is a special switch called ‘Two Way Switch’. The advantage of a two-way switch is the ability to control a single device from two separate locations. A convenient and apt use for them is for locations like stairways, a long corridor or a very large room.  This is a 2 switch for a single appliance. Two way switch has - State1/State2 (Single Pole Double Throw i.e SPDT Switch) which is the main element of the 2 Way Switching. It is a standard single pole double throw switch with three terminals. The one-way switch has defined ON and OFF states, whereas the two-way swi...
