Types of Electrician Qualifications

When looking at electrician qualifications they can include formal certification in different types of repair work, having a strong personal work ethics, and completing high school. The electrician certifications are usually received through regional training agencies but not all local areas will require this form of qualification. In this field of work post secondary school is not usually required but there are some employers that may look favorably on those applying for a job that has completed secondary school or they may even require it.

Most local regions will require that those working as an electrician must be certified by an exam that is region specific. The certification courses and written final exam that they must pass are often specific to the types of electrical repair work that they will be doing. All repair work is usually subdivided into categories. These can include:

• Commercial electrical repair

• Heating, ventilation, and air conditioning HVAC related repairs

• Residential electrical repair

When there are job postings they will usually include specific electrician qualifications that specify which type of certification the electrician has to have before they can apply for the job. If they are certified in residential repair they may not be qualified to do commercial electrical work. An electrician can be certified to work in any or all of the subcategories. This will increase their chances of obtaining work in one of three areas. There are some regions that do offer a general electrical repair license but it would require a bigger number of coursework hours along with a different final exam. This license would qualify an electrician to work in all available forms of electrical servicing. With this form of license you will only need to hold one license instead of multiple ones.

An electrician can also become certified in a certain area of expertise. This can be done by becoming affiliated with a trade organization that is local. You will also have to have on-the-job supervised training. The employers that work with individuals involved with this type of program may require that the electrician have received formal apprenticeship status in order to satisfy their electrician qualifications. You may also be required to complete all of the repair work under the licensed electricians supervision until the electrician has met the specified number of training hours are completed. How many apprenticeship hours that are needed to satisfy regional standards depends on what type of electrical repair work you are doing. You will also be required to take a written exam in order to receive their certifications. Personal qualifications can include legible handwriting and ability to get along with others.

6 Types of Electrical Conduits

Electrical conduits are used when installing new electrical wiring to help provide the route and give a high level of protection. It is made in many different materials, including fiber, plastic or mental and can be flexible or rigid. Here are a few of the most popular types of electrical conduits:

Galvanized steel

The galvanized steel conduit is entirely rigid to provide useful protection for the electrical wiring. This method is most common in industrial or commercial electrical installation. The typical length of the conduit is in the region of 10 to 20 feet, and multiple pieces are easily threaded together. Plus, it is easy to protect against corrosion by applying the right protecting paint. It is one of the thickest and heaviest in weight to make it a practical choice for the most difficult environments.


Metallic tubing (also referred to as EMT) is mostly made of aluminum or steel. It is more cost-effective and lighter than the alternatives in galvanized steel. This conduit is flexible to give more freedom in installation and a popular choice with industrial and commercial buildings. Also, the outer surface is naturally corrosion resistance, so there isn’t any need to provide a special coating.

Electrical non-metallic

The electrical non-metallic tubing is made of a thin, corrugated type material that is flame retardant and moisture-resistant. It has high flexible properties and is easily shaped by hand to fit the tight or awkward spaces. This is a perfect type of conduit for those in search of low labor costs and fast installation.

Flexible Metallic

The standard flexible metallic conduit is a practical choice for the dry environments and is simply a hollow tube with space for the electrical wires to pass through. There is also a liquid-tight flexible conduit in metal that has a waterproof coating. This is more practical for the damp locations and can be embedded in concrete or buried in other areas.


PVC is the most common type of conduit used for residential and commercial installations. It is a very affordable option and the PVC pipes are thick to give a useful amount of protection. PVC is naturally able to avoid issues with corrosion and resists moisture.

Aluminum Electrical

The aluminum conduit is a rigid option for the commercial applications and a practical option for areas that are prone to high moisture content. It is a useful choice to use in concrete slabs or walls, but cannot be buried in concrete because the alkali content in the cement can cause a negative reaction.
