A task as simple as changing a light bulb can become life-threatening with the exposure of an open wire. Careless DIY work with an open wire containing high voltage electricity can lead to serious injury
Serious injury or not, doing electrical work is certainly not for an unskilled and untrained do-it-yourselfer. Instead, electrical work is something that should be handled by a master electrician to ensure safety. Unfortunately, some homeowners remain unconvinced of the necessity of hiring a professional electrician when they think they can do the job themselves, and save money in the process.
Electrical work, though, is not as cut and dried as, say, doing laundry or cooking. In fact, according to About.com’s Timothy Thiele, many homeowners make mistakes when troubleshooting their electrical and wiring problems. Such incorrect practices can lead to fires and injuries.
A common DIY electrical job faux pas is using a wire with the wrong amperage when adding an outlet or circuit to a breaker or fuse. For instance, using a 14-2 NM wire that is meant for 15 amps to a breaker or fuse that’s designed for 20 amps. Master electricians are familiar with amperage specifications because of their training and experience in electrical work, safety, theory, and regulations.
If any electrical issue at home should involve manipulation of electrical wires, homeowners should steer clear of the job at all costs. For absolute safety, household electrical problems should be handled by trusted master electricians.
