Power Line Distance to Swimming Pool

[GoldDigger]

According to 90.2 (B) (5), a swimming pool can be installed under an existing service drop provided it's 22 1/2' above the water. Yes, owned by the utility company.
Conversely, it does not prohibit the utility company from installing a service drop over an existing pool. No mention of height above water it must be.
I'm guessing (hoping) the utility company would stick with the 22 1/2' in this case.

Here's a Mike Holt link covering section 90. Mentions what NEC does not cover under 90.2

And FWIW, there are no provisions in the NEC or NESC that require a utility to allow an installation which meets those clearances. They are free to impose their own stricter requirements, as long as those requirements are uniformly applied to new installations.

For pole to pole distribution lines, I can see a particular POCO wanting to get a wide horizontal easement over the whole distance for maintenance and maybe liability purposes. One such POCO restriction was mentioned in an earlier post.

It sounds like the OP is discussing distribution lines rather than just service wiring to the lots involved.

Take a look at the recorded utility easement on the deed of the property. What the owner does within that easement is more strictly regulated than what is done outside that easement.

True

I'm fairly certain the distance is for future servicing-just seems a bit wide.

This is the first time I encountered power lines in the rear of a property.

Interestingly enough, the property survey shows the power lines, but shows no setbacks/easements from them. The homeowner is very aware of this.

Surveys I have looked at over the years, have always noted an easement such as a water main, gas main or sewer. It was ALWAYS noted with a distance from the center of the utility on center, both directions.

My original post was dealing with the distribution lines and not the drop down service.

If the service drop and conductors are owned by the utility why does 680 even apply? 90.2(B)(5)

I agree that 90.2 does not allow consideration to what a utility does with there lines. i do not see how this is a trump card that takes away any consideration to existing utility lines

525.5 Overhead Conductor Clearances.
(A) Vertical Clearances. Conductors shall have a vertical clearance to ground in accordance with 225.18. These clearances shall apply only to wiring installed outside of tents and concessions.
(B) Clearance to Portable Structures.
(1) Under 600 Volts. Portable structures shall be maintained not less than 4.5 m (15 ft) in any direction from overhead conductors operating at 600 volts or less, except for the conductors supplying the portable structure. Portable structures included in 525.3(D) shall comply with Table 680.8.
(2) Over 600 Volts. Portable structures shall not be located under or within 4.5 m (15 ft) horizontally of conductors operating in excess of 600 volts.

It is a joke of a section

In most case those that set up those tents and portable structures have no knowledge of the NEC and there will be no electrical permits or inspections.

Here is a waterpark/splashpad/water cannons with a 27.6 kv. pole and lines located right beside it.

The question is who was here first and who is going to move--the local inspection director claims he is powerless to force a change--this issue is still in limbo for the last 5 years--someone is going to get killed or seriously injured.-----

There may be little enforcement of those sections, that still does not however make the NEC separation requirements from utility lines and swimming pools non relevant by quoting 90.2

That's just crazy.
You're right, someone will get killed or injured.

Would you let you kids go to that park?

As long as the lines do not fall, the sole cause for optimism is that kids are not likely to be climbing those poles and even at that voltage a water stream of individual droplets is not going to be very conductive. Plus the water cannons are probably effectively grounded which will minimize the touch potential.

That depends on the wording doesn't it?

It amazes me how folks strive to stretch the NEC to cover things that are covered by the NESC.

It does depend on the wording and there is nothing in the wording that supports the idea that when the installation is utility owned maintained and installed under that standard(NESC), the NEC installer has no responsibility to comply with NEC clearances called out in sections like the one currently being discussed.

The NEC does not govern the installation of utility owned installations it certainly governs equipment in close proximity to utility equipment and installations
