A device, composed of sharp points and/or knife edges, that discharges powerline overvoltages to ground. The term lightning arrestor is a misnomer, as these devices cannot protect against a direct strike to the powerline!
Answer for USA, Canada and countries running a 60 Hz supply service.It is a violation of code. When pouring concrete there is often a lot of pressure, not to mention boots, placed on wireways in the pour. This could cause the coil of the bx to separate, exposing the conductors to metal edges and to the chemical reactions of the concrete.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.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure 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.

If the outlet is on an outside wall there is a plastic boot that goesaround the outlet. The purpose of this boot is to keep the vapour barrier intact. The edges of this boot are then taped to the wall vapour barrier to make a complete air seal. The insulation goes behind the outlet boot which allows the wall R value to remain the same as the rest of the wall.

Originally, batons were flat, with very sharp edges. When conductors started bleeding all over their musical scores, it was decided to round these sharp edges and eventually the batons formed cylinders.
a clasp with serrated interlocking edges used for making electrical connections
Sharp edges and pointed parts allow concentration of charges and make it easier for the charge to arc.
Anything reasonably small. e.g. In the UK, the wood used in carpentery and construction is measured in millimetres for the smaller edges and metres for the larger edges.

one larger than the number
because the loss of positively charged particles is more in those parts
The Atlantic basin is getting larger with time because it is spreading from the mid-Altantic ridge. The edges of the basin are not subducting like, for example, the Pacific plate.
The Mollweide Projection shows areas that land masses are larger and they are larger. The disorts are shape of land and direction.

when materials get hot their molecules get energy,speed up and exert greater force on the edges due to which materials expand.
A pentagonal prism has 15 edges. 10 of these are base edges and then 5 lateral edges. Formula : A prism with a n-sided polygons at each end will have 3n edges.
