Therefore, electricians need to have a thorough knowledge of residential electrical. The demand for this installation will only increase, and end customers are looking for a balance between cost, benefit, and safety. Professionals who deliver all these characteristics will certainly have a happier customer base and, consequently, more closed deals.
What Is Residential Electrical Design?
We understand this project as a graphic and written representation of residential electrical installations: identification of lighting points, sockets, electrical circuits, and protection devices, among others. All this takes into account the equipment and appliances to be used daily, which vary according to the needs of each client.
Doing residential electrical work requires in-depth knowledge of NBR 5410. This standard provides for low-voltage electrical installations to guarantee the safety of people and animals, the proper functioning of the installation, and the conservation of assets. NBR 5410 applies:
- Electrical circuits supplied with a rated voltage equal to or less than 1,000v in alternating current, with frequencies lower than 400 Hz or 1,500v in the direct current;
- All wiring and all electrical lines that are not covered by standards relating to utilization equipment;
- To fix electrical signal lines (except internal equipment circuits).
How To Do Residential Electrical Installation?
The first step involves ensuring that the height of the boxes where switches and sockets will be installed, conduit passages, and position of frames, room temperature sensors among others, are consistent with the dimensions and technical specifications of elements drawn in the project. Afterward, the electrician must distribute the current between the points of lamps, outlets, and switches to the power panel or electrical command center.
Sounds obvious. But unfortunately, many professionals need to pay more attention to this and deliver work inferiorly. In some cases, this becomes a serious safety problem: without proper sizing, the risk of fire and equipment defects increases considerably.
Still, on safety, we need to talk about grounding. This procedure is mandatory, done through the earth conductor, that is, in contact with the ground. Thanks to grounding, electrical discharges, and current leakages have an alternative and safe path, protecting users against electric shocks.
Finally, electrical material stores that do not partner with good electrical material suppliers like Blackhawk Supply for example buy a little from different brands, which makes it difficult to guarantee the quality of the product to the end customer. In addition, it becomes more difficult to make your salespeople know all the products, which reduces service efficiency and undermines the credibility of your electrical material store.
