Installation of Safety Limit Switch
A safety switch is an electrical device designed to cut off power supply through a circuit whenever it detects leakage or loss of current from an electric system. A safety switch, therefore, serves as insurance against electrocution. It is purposely designed to prevent users of electrical devices from injury or even death. It keeps a check on the flow of electric current through a circuit. In case there is current leakage due to faulty appliances, switches, or wiring, it shuts off the power supply automatically. This action eliminates the probability of electric charges flowing through a person to the earth, thus electrocuting them.
Installation of a safety switch is therefore an inexpensive safety action that is intended to protect everyone and it is thus a life saver. It is such a crucial measure because sometimes we easily forget that our day to day electrical appliances can be fatal. An electric shock makes electric charges to flow to the earth through your body. This flow can be through your heart, interrupting the electric impulses which maintain a heartbeat, causing the heart to stop.
There are several types of safety switches. The three main types include:
Switchboard mounted switch. This offers maximum protection for your entire home. Lighting and all power circuits in your home are well protected by this safety switch. This should be installed by registered and highly qualified electrical contractors at the same point as your meter and fuses or circuit breakers.
The second type is the plugin safety switch. This is portable and can thus be taken outside, or in other locations where electricity is not usually used. This switch protects appliances that are only plugged into it. This plugs directly into an electrical outlet, thereby giving protection when a power extension cords connected with a power tool, or in situations that are prone to high risks such as outdoors and in locations like the areas surrounding the swimming pools that are always damp.
The third type is the power outlet safety switch. This offers protection to a single electrical circuit in an area of your home. This switch should be installed by a licensed electrician on the first PowerPoint of every circuit just after the switchboard.
A switchboard mounted switch is also ideal for garages and workshops to provide extra protection. The power outlet safety switch that provides single circuit protection is ideal for kitchens, workshops, laundries, bathrooms, nurseries, and other busy regions around your home. The plugin safety switch is ideal for a home handy-person or a trades-person who keeps on changing the area of operations. This is because the plug-in switch is portable and thus it provides portable protection. Examples of plug-in safety switch include heavy-duty cord sets and plug adaptors.
