The role of electrical contractors is critical in residential, commercial and industrial installations. Any electrical malpractice, which usually happens when unqualified electricians carry out the wiring, upgrades or repairs, may lead to serious accidents, deaths or fires.
While equipment faults are inevitable, how the system responds is critical as far as safety is concerned. Most electrical safety issues or risks arise due to equipment or wiring faults and malpractices.
In an installation with proper wiring and protection, the system will isolate the problem effectively and eliminate most of the potential risks. This works well as long as the electrician follows the best practices while complying with relevant codes and regulations.
Consideration when looking for electrical contractors
Besides qualifications, you will need to hire a licensed and insured electrical contractor with a good reputation, recommendations, and who is reliable and capable of delivering.
Find out the eligibility and credibility
Verify if the contractor meets all the legal, professional and safety requirements. Hiring registered, insured and qualified electrical contractors ensures that you are protected in case anything goes wrong. Good references from past clients mean that the contractor is reliable and you can trust them with your project.
The main issues to pay attention to includes;
License and Insurance: Ensure the electrical contractors are licensed and insured. In addition, they should have the worker’s compensation covers just in case there are injuries to the electricians.
Guarantee the work: Professional electrical contractors should have confidence in their work and will not have a problem giving a written guarantee.
Experience: The company and technicians should have the relevant experience carrying out similar projects. The experience requirements may vary depending on the scope and complexity of the work. However, it is advisable to settle on electrical contractors with at least 3 years of experience; complex jobs may require more years.
Availability: Find out about their availability. This is important before and during the project duration since you may require them to be available for discussions, changes or updates on the progress.
Documentation: Ensure the contractor will provide the documentation of the work carried out, together with diagrams that any other professional can follow and understand.
Will the contractor clean up after finishing the project? Professional electrical contractors will always clean up the work area and remove all debris, scrap parts, dirt and leave your premises clean and free of any obstacle. However, it is important to confirm before entering into a contract.
Reasonable pricing: There should be room for negotiation without lowering the quality of the work. Be careful with too low quotation since this may translate to low-quality products and workmanship.
Evaluate quotes from the electrical contractors
You may need to ask for quotations from a number of electrical contractors that meet your requirements. Evaluate all of them and shortlist about three that closely match your requirements. Ensure that these contractors meet all the standard electrical and legal requirements.
From here, you can now interview the shortlisted companies or candidates to determine who will best meet your requirements in terms of quality, reliability, flexibility, cost and other variables.
Be careful not to just pick the cheapest quote since it might not be the best, you will need to compare several factors before settling on the right electrical contractor. It is better to even pay higher than compromise on the quality of work.
Due to the risks involved, do not be afraid to ask the prospective electrical contractor questions which you think are relevant and important for the successful completion of the job. This will help you gauge the suitability of the person or company in delivering a safe and fully compliant electrical installation.
It is advisable to take time in analyzing the available options and then make an informed decision without any pressure. If in doubt, you may consider consulting experts or other people in the field.

Electrical wiring is used in practically all kinds of settings with all kinds of requirements. The truth is that a wire that is perfect for one application may not be the best choice for another application. But because they are in a wide range, you will always be in a position to select the best for the wiring project you have and any specific requirements there could be. Here are some of the factors that affect your selection.
Labeling – If you are keen enough, you will find that electrical wires have letters on them. These usually represent insulation types. For instance one labeled H means that it is heat resistant whereas one labeled HH means that is highly heat resistant. T could indicate thermoplastic insulation, N for nylon coating that is resistant to gas and oil damage and W could indicate that the wire is suitable for wet conditions. They could come with multiple letters to indicate the different properties. If you are not too sure about the kind you are about to buy, get professional help or make enquiries and go through reviews to find out the specifications.
Wattage load, ampacity and gauge – They are very important considerations to help you get the correct wire for the correct application. Wattage load indicates how much wattage it can accommodate, ampacity stands for the amount of electricity that can flow through the wire and the gauge is simply the size of the wire. These aspects are mentioned on appliances, making it easier for you to know which wires to go for. You can of course get assistance from an electrical technician if you are not too sure about the interpretations to help you find the most suitable one.
Size – Every application will come with a certain size that is suitable for installation. Wire gauge is what determines the size with the most common wires being sizes 10, 12 and 14; the higher the number the smaller the wire size. The size of your wire is important because it can affect the amount of power it can accommodate.
Color codes – When it comes to electrical wires, different colors serve different purposes. Black ones are commonly used for outlets and switches whereas red wires may be ideal for switch legs. Bare copper and green wires are for grounding whereas whites are always neutral. Some are best for all kinds of internal wiring, especially in appliances; your application should help you choose the correct color code.
Wire type – Electrical wires come in different types including triplex, panel feed, main feeder, single strand and nonmetallic sheathed wires. Your application again will determine which wire type is most suitable.
