yes the device must be grounded per NEC code. if the juncrion box is metal you must also sufficiently ground the box using a ground screw or clip. the ground box should be uninterrupted if the device is removed. (the device screws mounted to the box is not a suitable grounding means.
The term "fuse box" is typically written as two words when referring to an electrical panel that contains fuses.
Circuit breakers are typically located in a centralized electrical panel, which is commonly found in basements, utility rooms, or garages of homes and buildings. The panel is usually a metal box with a hinged door that can be opened to access the circuit breakers inside.
It depends on your local building code.
To turn off an electrical outlet, locate the circuit breaker panel in your home and switch off the circuit that controls that specific outlet. Alternatively, you can unplug any devices connected to the outlet or use a power strip with an on/off switch to cut off power to the outlet.
Are you talking about recepticale boxes that you plug a device into or service panel that the breakers are in?
In this case, flush means even with. For example an electric box could be mounted on the outside of your wall and would be an eyesore. Flush mounting recesses the box inside the wall and provides a flush mount for the outlet cover plate.
Most new installations in new homes will have this feature. It is for a "garburator" which is connected to the kitchen sink outlet. There is usually a switch mounted on the wall near the sink for switching it on and off. The switch is usually mounted in a two gang junction box. The other device in the junction box is an electrical receptacle.
That depends on what you mean by "box in". You must always provide access to an electrical panel.

== == If you're asking about the electrical socket outlet itself, usually two screws fix it into its wall outlet box.There are several ways to mount an electrical outlet box. Depending where you live, just go to your local Home Depot, B&Q, Homebase, Wickes or any similar hardware or DIY-supplies store and look around the section for electrical parts. If you're asking about the wall outlet box, usually 2 nails or screws fix it. If it's mounted into a hollow wall built using wooden wall studs and sheetrock/plasterboard, the nails or screws fix the box to the closest wall stud. If it's mounted into (or onto) a brick wall, the nails or screws fix the box to the brickwork.If not nailed or screwed to a wall stud in a hollow wall, an electrical outlet box can be held-in with a pair of "jiffy clips" or the box itself has flip-up ears that clamp it to the sheetrock/plasterboard. These types of boxes are known as "EZ-Boxes". As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any workANDalways use an electricians test meter having metal-tipped probes(not a simple proximity voltage indicator)to insure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Grounding is a direct path (that is, a wire, usually green) from the electrical outlet or switch back to the service panel, which sends stray current back to the service panel and then to the power plant along with the normal alternating current. This gives stray current a means to return to earth (which is what all electricity wants to do). If this path were not available, stray current would remain static until a pathway showed up (like, your finger, which would result in a shock). So, grounding protects you from dangerous shocks. Bonding is connecting any metal or electrically conductive material to a grounding wire. An electrical outlet is attached to a metal box. A grounding wire is connected to the outlet. Its purpose is to return stray current from any device plugged into the outlet--like a toaster--back to the service panel. Connecting the metal box that contains the outlet to the outlet's grounding wire also grounds the box, so touching the box doesn't give you a shock. The connection is made with a wire screwed to the box, then connected to the green wire grounding the switch or outlet.
An outside electrical box has a watertight in-use outlet cover so even when a cord is plugged in the outlet stays covered. That is the main difference between the outside box and inside box. An outside box also uses a ground fault circuit interrupter.
The box must be securely mounted. In some applications "Old Work" boxes are made to be secured by the sheetrock.

I don't know..... Go look in your box......SERIOUSLY.......
