Here is the what I saw as approached today's inspection:

Both Masts are under overhang which is about 7' 6" from the ground on that side of the building. The cablevision cable is running with overhead service from the previous pole.

The lowest loop is touchable flatfooted.

POCO notified.

Unsafe. Life safety hazards, both of them. Document it as such, and recommend immediate correction by a licensed electrician. Findings like this often prompt me to comment that I don't like to read about my clients in the newspaper . . . in the obituaries.

Wow. And certainly within 3 feet of an operable window.

One would think that the meter readers would have some responsibility in notifying their supervisors of those conditions when they were out reading the meters.

I agree. Nowadays (and likely in these meters also) they have no more "human readers", as their all digital and read via RF.

In this case that statement may be correct but don't assume that it applies to all windows! If a window is capable of being used as an escape from the building, which it most certainly is here, that rule applies. However it does not apply to an awning type window or a window that cannot be used as an escape from a building.

The riser definitely needs to go through the roof for proper clearances!

Lou, everyplace I've ever worked the rule is that if the window can be opened at all the 3 foot rule gets applied, even casement windows that open toward the mast. The reason is that if someone can get an arm through anywhere and touch the wire there is a safety issue.

Bill is correct, and, unless I've missed it all these years, the NEC has never mentioned emergency egress regarding windows being within that 3 feet.

The cable TV cable?


The cablevision cable is running with overhead service from the previous pole.

Some places they tie the GEC to the ground rod, and sometimes water pipe, to the neutral at the top of the mast. Size says they did something like that here. Need more info to tell exactly what's afoot.

I hadn't noticed the second tap on the neutral. I looked some of my other photos. It goes down to ground. Several connections there. Cable, phone, ac unit. Good eyes.

Not NEC, FBC or FPL standards maybe? I forget where I found that but I have successfully argued this with Miami-Dade on more than one occasion! I will look for it but there are other exceptions in NEC. Bold and underlining by me.

(A) Clearances. Service conductors installed as open conductors

or multiconductor cable without an overall outer

jacket shall have a clearance of not less than 900 mm (3 ft)

from windows that are designed to be opened, doors,

porches, balconies, ladders, stairs, fire escapes, or similar

locations.

Exception: Conductors run above the top level of a window
shall be permitted to be less than the 900-mm (3-ft)
requirement.

all the talk about windows and the code and nobody mentioned the requirement for the overhead lines to be 10 foot or more off the ground.

Ken,

The original post started off there, stating that those were only 7' 6" high, and ended by stating "POCO notified.", guess we pretty much presumed that he knew the minimum height as he notified the power company, and that he was just posting this for us to see.

I've seen them so low you could clothesline yourself on them if you were not paying attention - a 30" high deck had been constructed underneath the overhead service drop, which was less than 8 feet high to start with.

Looks like your right from the additional picture. I thought it had to be GEC related but that is just really rare in my area to connect in that manner . In most all cases its the service equipment in my area and occassionally the utility allows inside a meter enclosure.
