“If you can block blue light, you can actually create something called circadian darkness or virtual darkness” says Researcher Dan Pardi in an Studies have shown that by wearing these amber-tinted glasses, you can produce almost as much melatonin as if it were pitch black, even in a fully lit room or while looking at a bright screen on your tv, phone or tablet.

The list of rules to be followed when installing new electrical systems into a building are related to the specific rules of the state, as well as certain minimum requirements laid down by Federal law. So in some senses the United States does not have a unified Electrical Building Code, because often there are variations between different states.

It was to address exactly this issue that the National Fire Protection Association, a panel of nineteen different bodies, began publishing the National Electrical Code (NEC) in 1897, and now every three years, in order to arrive at a single source of rules that should govern electrical installations. The current version was published in August 2010 and runs to over 1000 pages.

Whilst the NEC is not law as such, in practice it has been adopted by most states as their set of rules for electrical installations and wiring in buildings (with a few changes here and their depending on the state you are in), and so is now in practice the Electrical Building Code for the United States.

This is the book that all Journeyman Electricians will consume when undertaking their training, as it is pretty much the standard version across the country.

Though there are some differences between the states, and you can see the individual requirements for your state here: State Regulations

Some of the key NEC rules that need to be followed when installing a new electrical system into a building are:

If you are planning on installing electrical wiring then you should refer to the NEC and your local Electrical Building Code for specifics and to the link above for any state specific requirements that you need to know.

For some, flickering lights are an annoyance and can be a distraction. Others don’t notice the inconsistency in the lights. But, that fluctuation in light can signal problems in the circuitry or light fixtures in one’s home. Depending on the source of the problem, it could lead to serious safety issues in a home.

All lights flicker to some extent, based on the amount of power that is coming into the lines in your home.  If your lights flash or flicker regularly, it’s often a sign that there’s a problem – either in connection or power use. Situational flickering – like when an air conditioner starts – is a sign that there’s an issue with power supply. Simply put, the dip of the lights when the AC unit starts up occurs because the AC pulls the available electricity supply from the light. It’s usually temporary. It may also be a sign that the outdoor AC unit isn’t wired for maximum amperage. If the flickering lights aren’t related to a large appliance powering up and running, it’s a sign that there are issues – home may be brighter and more comfortable.
