Poor spelling but the nail got hit on the head here.

That is standard building code for electrical outlets. And, it is to prevent issues with minor flooding and power meeting and having a conducive relationship.

Cable, and phone, outlets should be 12-18" from any power outlet as well. Electical interference can cause low frequency ghosting and in some cases, packet loss if the noise floor is raised over -20dBmV. I have fought some hard nosed battles with customers that swear their issue is caused by our plant when, in fact, it is their own electrical outlets that cause the issue.
We just spent 5k furnishing our new house here in BA, Ok. I'll have to toss some pics up here in a few days when the crap gets here.
Looks great Rip!
