Is it possible for a wire to arc with a nail? The u-nail that hangs the wire to a wooden support beam looks like it was hammered in too far and may have cut through the insulation around the wire. Is this a fire hazard or can I leave it as is?
Hello, anytime the insulation is broken on the line it can be a potential fire hazard, and yes they can arc or short out. The potential may not be large but with fire it safer to err on the side of caution. Codes vary around the country so check there, but we typically pull the staple and determine how deeply the insulation is really compromised, if it is only through the external shielding an in-expensive way to safely repair it is with a shrink tube type of product. However, if any of the internal strands have been compromised the line would need to be cut and a junction box installed and the wire spliced back together inside the box. Hope this helps:-)
Stark seems to apply Palladium isotope from his missiles with the aid of fact the reactor's gasoline. as quickly as the reaction starts, the potential harnessed is enourmous at 3 GJ/s or such as 3 GW. (that's greater suitable than two times potential required for time-vacationing (which needed basically a million.21 GW of potential) in returned to the destiny action pictures). This potential may well be used to potential up his journey for a protracted time for his superior reactor, no longer the 1st one. To make this somewhat useful potential furnish, i think we are able to. and that i think that could be a threat. yet i think of that that is performed basically in some hundred years. The action picture is basically fictional and that i think that the author are basically fantasizing regarding the appropriate potential source. (desires specially grow to be actual at last). If we live in nineteenth century, human beings won't have confidence you in case you may deliver sound wave and photos accross the globe. Now, that could be a threat. So what makes an arc reactor impossible? that is performed. yet no longer in recent time.
Did it cut through the outside sheathing or one of the conductor sheathing? If its just the outside sheathing, remove the staple and secure the wire further away. Use electrical tape and wrap the cut...If it has penetrated one of the inside conductors, well, without seeing it its hard to tell you. The biggest concern would be if the wire ever overheated there is less 'insulation' to prevent it from burning into a neighbouring wire. Err on the side of caution. More detail would help.
If you're talking about Romex cable, and a staple of the type commonly used to anchor it, some shock or fire hazard might exist. It's hard to tell without seeing the case. The cable consists of two or three insulated wires and a bare copper ground covered by an outer plastic jacket. If only the outer jacket of the cable is crushed or pinched, the danger is minimal. If the inner insulation of the wire is compromised there might be trouble. If you think this is so, show it to a 'Pro'. No-one can responsibly advise you without 'eyeballing` the situation.
Electricity moves very similar to water it will always find the path of least resistance. So yes if you cut into the wire you will energize the u-nail. Your best plan is to remove the nail carefully while there is no power in the circuit examine the wire and if there is a cut through the insulation replace the wire. I say this because from your question it sounds like you are in the electrical rough in stage. You can install a J Box there but by code it must be accessible so that would mean there would be constant reminder of the problem in the wall.
