240 volt electric receptacle outlets

It is important to identify different electric receptacle types that will help you in replacing and fitting electrical outlets before involving yourself in a home improvement project which involves installation of electrical fittings and outlets. The chief function of the electrical receptacle is to tap the electrical circuit and provide power at a given location. Different electric receptacles are available in power mounted or flush designs.

Generally according to the code of electronics, the receptacles that are used in home for 15 or 20 amp powers should be of three prongs and of grounding type design. Most of the common 120 volt receptacles are of the same design. It is important to check the appliance voltage before inserting its plug into a receptacle.

A 120 volt appliance should not be plugged into a 240 volt receptacle and vice versa. A 120 volt plug is generally a three throng plug with a basic design while the 240 volt plugs are bigger plugs and are used in special 240 volt receptacles only. Receptacles are used with copper or aluminum wire. Those receptacles which are marked AL-CU can be used with both copper and aluminum wires while those which have an AL symbol marked with a slash can be used with copper wire only.

Different types of electrical outlets in home needs to be fitted with different electric receptacle types. Outlets in the outdoor area where there is a possibility of getting in contact with water and in kitchen, bathroom etc. is fitted with GFCI receptacles that stand for Ground Fault Circuit Interrupter.

These receptacles also protects against ground faults that may occur due to contact of human body with a live electrical wire. It trips the power supply quickly and prevents any major accidents. These GFCI receptacles need to be checked periodically to prevent any malfunction. Identifying these receptacles is easy as they have two narrow slots, a half round hole and few testing buttons.

For other home areas where there is no chance of any water contact, standard electric receptacles can be used. These standard receptacles have a half round hole for ground plug and two narrow slots but do not have the set of buttons. Appliances with three prong plugs can be used with two prong adapters. Large appliances however, use larger receptacles which have different configurations and can have two or three narrow slots and a half round hole in it.

Once you identify the electric receptacle types, replacing or installing the receptacle becomes a much easier task as you have the set of instruments and replacement receptacle ready for that particular type of receptacle.

    If you are installing new electrical outlets you should consider sending a couple of more bucks and picking up fire prevention outlets. it is just one less thing you will have to worry about. I install them on all the houses I work on now. It just seems to make sense to me.
