A modern convenience often taken for granted, electric power, can be found everywhere. To route electricity from the power station to your wall outlet requires many steps. Residential house wiring includes a variety of wiring and control devices to ensure safe and reliable service.

Electricity in the home is distributed by means of branch circuits. Furthermore, each branch circuit is supplied via a circuit breaker sized per the expected load on the circuit. A typical lighting and receptacle circuit will be rated at 15A. Because of their size, larger loads like ovens, clothes dryers, and air conditioning units are given dedicated circuit breakers.

A typical home can have dozens of 15A circuits, and several 20A, 30A, or even 50A circuits. Yet the total of all these breakers is much more than the size of the main breaker. However, this is intentional. It’s highly unlikely that every circuit will be fully loaded at any one time, so a demand factor is taken into account to keep the main breaker at a reasonable size.

A wood-framed home will typically use solid copper non-metallic sheathed cable for the majority of wiring applications. Solid conductors are easy to terminate and cheaper than equivalent stranded wire. The AWG size of the wire is determined by the expected load on the circuit and by the size of the breaker protecting it. You should never connect a wire to a breaker that is too large to protect it, as an overloaded wire can easily catch fire.

Packard describes hospitals as being historically “institutional and very uncomfortable,” and her mission is to educate the public on the “importance of design” to patient health.

intrinsically photosensitive retinal ganglion cell in the human eye, which senses light and regulates the body’s systems, including melatonin levels, which are directly related to sleep. Visa’s Amber Night Light, she says, creates ambient light that won’t disturb the intrinsically photosensitive retinal ganglion cell. This allows nurses to check on patients without disturbing their sleep.

Of course, all this valuable information leads us to the problems solved by Visa Lighting’s healthcare light fixtures. Packard calls special attention to the benefits of using LED fixtures. She reminds us that LEDs are indeed a great option for hospitals because they are energy efficient and therefore save money, reducing the cost of healthcare; they render color well, which is necessary, so that doctors and nurses can accurately assess skin pallor; and, unlike fluorescent lamps, LEDs contain no mercury.

Whether you have a scheduled lighting project or an emergency on your hands, there are plenty of situations when it’s appropriate to call in a local electrician. For your safety and sanity use a certified electrician that can provide quality work and can be counted on for years to come.

Repairing a Wire Damaged from Drilling a Hole in the WallWhether you’re hanging pictures, shelves or a TV mounting bracket—or any other reason you might be drilling into a wall—there’s always the possibility that you’ll hit and damage a wire. This is definitely a fix you want to leave in the capable hands of a certified electrician.

To prevent the problem from happening again, use a stud finder and aim for the center of the stud. Before drilling, use a small tipped screw driver to verify you are hitting the stud and not the side. Once you have verified, feel free to drill away.

From the National Fire Protection Association, there were 1235 revisions made since 2014. First of all, code-making panels from the NEC created these revisions which were submitted to the NFPA for consideration. Below, find some of the NEC code changes that were proposed and/or made to electrical safety codes.

This change requires the branding of any reconditioned equipment, Furthermore, descriptive markings, trademarks or name must be displayed. Additionally, it enables the recognition of the responsible organization that carried out the re-branding.

Most noteworthy, with the changes in this code, any electrical equipment would be traceable from its worker or buyer.

Added to cover any electrical equipment located in a cramped place. This includes:

This change was directed at checking the provisions of equipment used in limited spaces. Also, it addresses compliance of crawl spaces and ceiling spaces.

This is a general review of 110.26. For any type of working space, conspicuous and permanent signs should be provided.

The above code changes should be followed by engineers, architects and designers. The new NEC Code Changes were developed to avoid complications or unlawful/unsafe activities in the workplace.
