Some Common Electrical Codes
A lot of people do electrical DIY to either save time or money or both. Not being aware of the electrical code can lead to you doing things that are illegal and potentially dangerous. Here are some common codes that you should keep in mind before starting electrical work by yourself at home.
Separate circuits are laid for each socket in the bathroom and there are usually multiple numbers of these, as people need to use razors, straightening irons and hair dries possibly together. A dedicated circuit is also present for the light, fan and heater. Sockets have to have GFCI protection.
In the kitchen too, separate circuits are required for each appliance that has a motor and this includes microwave, fridge and dishwasher. If you have an electric cooker, you need a 240- volt circuit meant only for it. The counter top should have a minimum of two GFCI receptacles.
In the bedroom, there must be switch close to the door to turn on the light as you enter the room. A pull chain switch is acceptable for a desk lamp or a wall lamp but for a ceiling lamp, a wall switch is a must. Closets must have globe-covered lights controlled by wall switch.
While the paragraphs above covered some of the general codes, those below detail some avoidable DIY mistakes that aren’t just unlawful but also dangerous. Wires passing through wooden frames need to be at least 1- inch away from its surface so that nails do not accidently ruin their insulation. If this happens, it will result in a short. If keeping this clearance isn’t possible you should install nail plates around the framing face to protect the wires.
Parallel runs of line- and low voltage wires cause interference in electronics and/or communication, such as TVs and telephones. Also, any un-insulated contact between low- and line-voltage wires in a box can damage equipment or cause a fire. 6 inches of space must be maintained between these and they mustn’t be brought to the same box, especially if the box doesn’t have an approved divider.
Putting several wires into a tiny box will cause them to overheat, melt the insulation on them and eventually cause a short or a fire. To avoid this, you should use more boxes or a bigger box. Mud or plaster rings can also be used.
Another thing that becomes an issue when electrical wiring is not laid properly and causes damage is policy that dictates when you can claim insurance. If a person other than a licensed electrical contractor has done this, you are sure to not get any money from insurance. Allowing just anybody to do electrical work for you is sheer carelessness on your part. You yourself must know what the codes prior to beginning electrical DIY projects.
