Guide To Electrical Wiring Of Your Home – Steps, Code, Material, Tools
What to know before installation
Then there’s the safety and danger aspect of the installation of electrical components. In most instances when installing electrical equipment power is located and disconnected. Ensuring the installation can be accomplished safely without electrical shock. There still ends up being the risk of incorrect wiring. From an intolerable unbalanced load, wrong neutral connection, improper grounding or bonding, and many other code violations.
I could make a book just on all the service calls I have been to that had an extremely dangerous and/or outrageous wiring. One service call from years ago I got called in for a fluorescent light in a kitchen not turning on.
So when I arrived at the house the customer takes me to the light. He tells me that he changed the fixture himself and that it’s not working. Right away assume, “oh, he must of connected a wrong wire, easy fix”. I turn off the switch and go to open the fixture and immediately upon touching the outside of the fixture I get a shocking surprise. A nice electric shock from touching the base of the fixture. So, at this point, I locate the breaker and disconnect the entire circuit. I open the fixture to find a hot wire, not the switch leg, tied directly onto the bonding of the fixture. I of course redo the connections, turn on the circuit and test for proper voltage and function of the light.
That is one of the tamer stories, as I have seen many code violations throughout the years from self installers and fly by nighters. The point is, even if power is turned off and you can accomplish a safe install. In the end when power gets connected to your new circuits there is still risk of improper installation. It could mean arching from poor connections, power on metal enclosures from improper connections, or any number of things. This is why it is extremely important to know the code rules for what you are wiring. As well as have an understanding of how circuitry works. We wont go into the depth of the dangers of electricity here, but there is a lot of information on it. The extreme heat that can be caused from a small arch is more than enough to start a fire
When your roughin electrical wiring is completed it is time for your inspection. For wiring done in your own home, most municipalities allow for you to obtain a ‘homeowners permit’. If you are having a company work on your home or business, they must obtain their own permit. Be prepared, when you have done the install to know the installation as the inspector will want to go through the what and how. They will confirm that important safety factors and code are in compliance. If there are deficiencies, you will need to correct them and most likely call for a re-inspection.

Old Electrical Wiring Types, History of Electrical Wire Types
History of electrical wire & electrical wiring: how to recognize knob and tube electrical wiring and unsafe “extension cord” wiring. How to evaluate the number of electrical circuits in an older home. Photo guide to types of old building electrical wires.
In this article series we list common old building electrical wiring system safety concerns and we illustrate types of old electrical wires and devices. This article series answers basic questions about assessing and repairing the electrical service, capacity, wiring type, condition, and safety in older homes.
Photo Guide to Old Electrical Wire Types
“So much has been said and written upon the subject of high-tension electric currents and their probable or possible danger to human life, and so many different opinions have been advanced by men whose positions serve to surround their utterances with an atmosphere of knowledge of the matter under discussion, that the mind of an unscientific public has been unable to come to any definite conclusion upon the basis of “expert” testimony.
These rusty looking “pipes” may be the last remnants of the oldest and original electrical wiring used for underground electrical power distribution in the U.S. We describe these electrical power cables and provide images of and links to early electrical wiring and wire insulation methods in this article.
In the electrical wire history & old wire identification article below we illustrate a variety of types of electrical wiring found in older buildings based on the wire insulation material (asbestos, cloth, plastic, metal) and the wire material itself: copper, aluminum, copper-clad aluminum, tinned copper.
GUIDE TO DIY VAN BUILD ELECTRICAL: HOW TO INSTALL A CAMPERVAN SOLAR ELECTRICAL SYSTEM
When we first started thinking about our vanlife electrical system and buying our components, we had a lot of questions. We researched online, read other van build blogs and forum posts, and watched Youtube videos. Some were very helpful, but many left us with a swirl of even more questions.
We were learning a lot about circuits and electrical systems, but we were also overwhelmed by all the new knowledge coming at us from all directions. Electrical is such a vital part of any van build, and we wanted to get it right.
In this post, we go over exactly what we bought, exactly how we connected everything, and we even have pictures and diagrams (yay)! For those of you interested in further reading, we also include links to blog posts and other resources that helped us out along the way.
Obligatory Disclaimer: This post describes what we did with our own system based on our own research, and we hope you’ll find it helpful. That said, we are NOT ELECTRICIANS. Working with electricity in any form can be dangerous. It’s always a good idea to read the manuals for all of your components and consult with a licensed electrician before performing any electrical work.
