The following five violations of the electrical code are some common examples you may come across. Do not take any chances when it comes to your home's wiring! Call an experienced electrician if there is evidence that someone has tampered with wires inside or outside, because they put both people and property at risk:
Insulation Touching Unrated Recessed Lights
If you have any recessed lights that come in contact with your attic’s insulation, make sure they are rated for an IC rating. This means there should be at least 3 inches of space between them and the IC-rated material on top (or bottom) coats like gypsum board/plaster walls etc... If unsure consult a professional!
Overcrowded Wires
When wiring a house, it's easy to get carried away with the temptation of cramming 4-5 wires in that tiny hole. However, this results in damage and may not be noticed until another wire drags next to its neighbor(s) creating exposed conductors which can cause fires! As per standard practice there should only ever been 3 wires per 7/8 inch bore - leave room for any shifts by using larger holes or adding junction boxes where necessary
There's nothing worse than coming home from a long day of work to find that your lights are out. It can make for some frustrating moments as you wonder what might have caused the power outage and if there is anything else wrong with this old house! Well, no need worry because now we know: putting newer light fixtures into an old wiring system will overload its capacity resulting in overheating which leads us back full circle - too much heat means they are more combustible which is dangerous.
Illegal Splices
One of the most dangerous violations is a splice, connecting two or more wires. These can be very easily done incorrectly inside an electrical box if you don't know what you’re doing and could cause major problems with safety brackets being pulled out.
Technically only qualified electricians should be working on this type of thing and should ensure they are always following the electrical code.
Knob and Tube Wiring Issues
Wires in your home can be a fire hazard because they aren’t grounded and only support lower amperage. This kind of wiring was called "state-of the art" when it first came about, but now with today's power guzzling gadgets that need higher pressures to work properly (and often times produce more heat) this type has become outdated - leading many homeowners down an unsafe path due their lackadaisical insulation which easily degrades over time.

HOW TO AVOID THE MOST COMMON ELECTRICAL CODE VIOLATIONS
The National Electrical Code (NEC) is established by the National Fire Protection Association and has been adopted in all 50 states across America. In addition to the national code, which states have their own ways and degrees of enforcing, states and localities often have their own set of standards for electrical wiring and installation.
Nails and Screws Going Through Electrical Components
Nails and screws, as mentioned in the NEC, are used to secure electrical components but must meet certain criteria in order to be up to code. They must be applied to the back or one side of the component, and if they have to run through the electrical box, the wires in the box must be protected to eliminate the possibility of insulation deterioration. If the wires and insulation are not protected from each other, it once again increases the risk of starting a fire.
