For many people the basement is a place of escape and for others it is simply a place for storage. With all the room underneath you, you don’t want it to go to waste. Renovating your basement can greatly increase the value of your home if it is unfinished or in need of an update. One important point to remember is the electrical wiring hiding behind the walls.

If you bought your home and it was already finished, that work could have been done many years ago and you might be thinking it is time to update fixtures, paint, and maybe evening moving a wall. When you begin pulling things apart, be careful for loose or old wires. If the electrical work was not done right, there could be loose electrical wires that were not tied in properly.  The wiring can also be old and out of date. If you are moving walls or replacing fixtures and you are worried about the age of the wiring, have a licenced electrician come to inspect your wiring. If you are going to go through the effort of redoing your basement you want to make sure it is done right.

For those who have an unfinished basement you have a clean slate to work from. Once you start putting up the framing for rooms, you can start on the electrical rough in. This is the foundation for the electrical wires, which includes drilling holes in the framing and running the wires to where they need to go. If this is not done correctly it could leave you with a significant headache once your drywall is up and you have to punch a hole in the brand new wall.

When you are planning out your new layout, make not of where each outlet, light switch, and light fixture will be placed. This will help you plan out the electrical rough-in. If you have reached this point in your basement renovation and don’t know where to go from there – contact Expert Electric. Our electricians can help you with the planning and running the wires through your basement.

Most electrical panels are located in the basement. Prior to your renovation, you probably could easily access the panel. When you are putting up framing and drywall, be sure to leave enough room around the panel for it to easily open. You also want to make sure not to cover it with furniture that could prevent you from accessing it quickly. In the event that you need to turn on a tripped breaker or even turn off a circuit in an emergency, you don’t want to be struggling with furniture to get the panel open.

Before you renovate your basement, have a plan and be prepared.

Electricity exists everywhere, from high voltage power lines to phones and computers. Understanding the basics of how it works remains essential to using it safely and efficiently.

When electricity travels from a positive lead to a negative lead in a circuit powered by a battery, it is considered direct current. This type of current powers electronics, LED lights, and cars. Alternating current is generated from rotation, usually by a generator. The direction of the current and the voltage flips as the generator completes a rotation. The faster the generator spins, the faster the flipping of current direction occurs. In North America, the typical frequency of AC power is 60hz or 60 alternations per second. The advantage of AC power is that the voltage can be stepped up easily by use of a transformer, which allows high voltage transmission. AC power is also useful for electric motors.

Specifically, power is a measure of energy usage over time. The standard unit of power is the watt and calculated as P (watts) = V (volts) x I (amps). Utility companies sell electricity in units of kW*h (kilowatt hours), which is simply one kilowatt of power delivered continuously over one hour.

A variety of ways exist to quickly and efficiently complete an electrical installation. One method involves using pre-made and pre-fabricated conduits, cables, panels, and devices. Pre-fab strategies cut down on repetitive labor costs and scrap material waste.

Furthermore, pre-fabricated components are assembled in quality-controlled factories by highly trained technicians. This ensures that every device and termination is in working order and properly connected. These technicians work faster and cost less per hour than a journeyman electrician, therefore saving the contractor time and money.

Another option to increase efficiency involves using pre-wired devices. They can be used for repetitive tasks like receptacles, switches, light fixtures, data ports, or fire alarms. They save time by eliminating the need to terminate each device individually. Instead, boxes are made to order and ready to install. The desired length of cable is attached and ready to run to the nearest junction point. Simply attach the box, route the cable, and connect to the supply wires. Most suppliers prepare a custom quote, further reducing time spent by the foreman planning and ordering parts individually.

Pre-wired panels are possibly the simplest way to save money, as they require no special tools. Wiring up a panel at the shop before heading to the job site allows you to function test it before installation. This ensures proper functionality. In addition, it keeps the interior of the panel away from weather and other possible sources of job-site damage. For larger or more complex panels, suppliers can be arranged and have the work performed by specialized technicians. Panels can even be ordered with pre-cut and pre-terminated lengths of cable or cord.

Most electricians have used pre-formed conduit, especially PVC which requires specialized tools to bend. However, entire runs of pipe can be custom ordered and pre-shaped. Especially useful in underground conduit networks or when complicated bends are required, these pre-made conduits drop in place and fit perfectly to the engineer’s prints. They also ensure that conduits are not damaged or kinked during the bending process and that no sharp edges or rough spots are left to damage wires or cables.

If the project demands it, entire buildings can be pre-made and pre-wired in a factory setting by trained technicians who specialize in quickly and efficiently preparing custom ordered buildings. Especially useful in industrial settings, these buildings come complete with all interior and exterior lights, switches, receptacles, and control wiring.

Often, motor control centers (MCCs) for large industrial installations are constructed this way. Therefore, on-site electricians are free to begin immediately running cables to motors and devices, with simple termination points inside a completed building. In addition to using fewer electrician hours, they also reduce required hours from other tradespeople such as welders or cladding installers.

Finally, pre-fab strategies are a great solution for reducing material waste, worker hours, and downtime while making deadlines a snap. Projects run smoother with fewer errors.
