Start by checking your neighbours, it may be a utility issue. If it is just
your house you can check your main switch in you panel to see if it needs to be reset. If that does not fix the problem, call your local utility.

You can check the main house panel to see if a fuse has blown or a breaker has tripped. If that does not solve the problem you can check GFCI outlets (the one with the reset button, usually in bathrooms and outside) to see if it has tripped. If this does not fix the problem you should contact an electrician.

Unplug everything and turn off all the lights on that circuit. Then try to reset/replace the fuse/breaker. If it still does not work the problem is in wiring and you should call an electrician. If the circuit resets then plug things back in and switch the lights on one at a time – if you plug something in and it trips the circuit the problem may lay in the item you are using. If you cannot find the problem with this method, you should contact your electrician.

An electrical junction box is a container for electrical connections, usually intended to conceal them from sight and deter tampering. A small metal or plastic junction box may form part of an electrical conduit or thermoplastic-sheathed cable (TPS)wiring system in a building.

A wiring diagram is a simple visual representation of the physical connections and physical layout of an electrical system or circuit. It shows how the electrical wires are interconnected and can also show where fixtures and components may be connected to the system.

You only need to install carbon monoxide detectors in your home if you use natural gas.  If you do, you need to have one on every floor and within 15 feet of the bedroom doors.

Per the National Electrical Code, you must have 1 smoke detector on every floor, 1 inside each bedroom and 1 outside each bedroom.

The Environmental Protection Agency (EPA) has a section on their website explaining how to recycle and dispose of fluorescent lights.  It is best to call your local garbage/recycling company and find out what facilities are available for disposing of fluorescent lights in your area.

If you look closely at your ceiling fan fixture, you will see a switch on the fixture that changes the direction the fan rotates.  When the fan rotates in one direction, it forces the air down to keep you cool in the warmer months.  When the fan rotates in the other direction, it forces the air up which pushes the warm air at the ceiling down into the room to better distribute the warmth during cooler months.

Tamper-resistant plugs were introduced in the 2008 National Electrical Code changes.  Any plug that is changed in a home must be replaced with a tamper-resistant plug.  Tamper-resistant plugs look just like regular plugs except they have plastic guards in the straight openings that prevent you from being able to stick something in one or the other.

You must be plugging something into both openings at the same time, or you will not be able to get anything in the plug.  Of course, this was done to help prevent children from sticking bobby pins or other small metal objects into the “hot” openings of your plugs
