Hole in Service Entry Wire


I accidentally drilled a hole in the service entry wire a few months ago. Other than the light briefly flickering when it initially happened but other than that I hadn’t caused any problems at all. I know I got extremely lucky! I got a quote from an electrons of 925$ to replace it but I’m wondering how badly it needs to be replaced since it hasn’t caused any problems?

Re: Hole in Service Entry Wire


By service entry wire, do you mean one of the service legs?

It is hard to know for sure, but you may have severed one of the conductors reducing it's capacity. It could also short out in the future causing a potential fire. Glad you are ok,!

Re: Hole in Service Entry Wire


Without at least seeing a picture of the damage or an accurate description
then we cannot say for sure.
Depending on the depth of the damage you can reduce the wires current carring capacity and also it's mechanical strength.
Also if water getts in then corossion is likely.
Most Electricians will be shuddering now !

Re: Hole in Service Entry Wire


You're very lucky. A man in a neighboring town was killed when he did that a couple years ago. He was drilling out through the sill from in the basement and drilled right into the conduit between the meter socket and the panel.

Personally, I'd almost guarantee that I couldn't sleep in the house with it like that.

Re: Hole in Service Entry Wire


I'd be worried about the insulation having been cut (that's the "jacket" of plastic like material) it's the part that stops the current from getting out of the metal wire (a bit of a laymen explanation)

I'd think it'd be a fire hazard...

Re: Hole in Service Entry Wire


If the light flickered when it happened then you definitely damaged the insulation on at least two of the wires inside the cable. It should be replaced.

Re: Hole in Service Entry Wire


Are you talking about about a cable (2 or more wires) or a single conductor.?

This is one of the most ridiculous threads ever. Replace the conductors. Full stop.

Yeah, and my girlfriend is just a "little bit" pregnant... maybe I should wait?

Perhaps the fire will burn out by itself...

Sorry - I don't mean to be disrespectful - OP has a problem and did ask, however, there is NO WAY to let that wire stay unrepaired.

Re: Hole in Service Entry Wire


Well I do think a couple layers of electrical tape can fix some nic situations, this just isn't one of those types of situations. Personally, I just replace all nic's if they're going to be difficult to access, like a Romex nic (in wall) I'd defiantly replace, but maybe a lamp cord nic I might tape up - depending on how often said lamp cord is moved, and how easily I can make sure the tapes still sticking (they stop sticking after a while.) I'd never tape up an extension cord though because you roll them up so often it'd lose the tape, etc. Situational...
