Hi Ted

Just to give you advance warning this is a home inspectors site and not a homeowner do it yourself help site. You need to correct several things from what I see in your description and photo's.

Someone here may decide to give you guidance but I'm going to defer to others as there has been complaints about advising DIY here.

However here are two very good sites for you to post your questions ...

I'm not yet committed to a DIY project or hiring it out. It's within my capabilities once I understand the code. Assuming that someone paid a journeyman electrician to do this existing installation and that it passed inspection, could I do worse?

Guess that HI didn't know much about pools ...

I do not think a licensed electrician did the electrical work on your pool...

Anyway here is a free download that should be current to the 2002 electrical code. there are some changes in 2005 and 2008. Also local code has a lot to say about how the pool is installed so check both sources.

Without looking at the photos, here are some answers.

SOMETHING is wrong as the REQUIRED working space in front of the panel does not allow for ANYTHING to be in that space, which is REQUIRED to be 30" wide by 36" deep in front of the panel, and that there be an access route to that space, basically the same width, but maybe allowed to be 22"-24" wide.

2. Does the 15 amp dual breaker to the pool pump have to be GFI? Do these motors run on a GFI breaker, or is there too much electrical leakage and the breaker will nuisance trip?

That would not be a "nuisance trip", that would be a "life saving trip", you DO NOT WANT TO USE A POOL PUMP with that much leakage current.

I don't know you, you don't know me, so let me just say this - When dealing with swimming pools a little knowledge is sometimes a bad thing... so it's possible that you don't even know what you don't know, and that can be deadly. So please consider hiring a professional.

There's lots of special wiring at swimming pools - wiring that is not common anywhere else in a home. It's advanced wiring and not something for beginners to experiment on. Most homeowners and DIY'ers have no clue. There's a reason why many inspectors don't inspect pools and why many licensed electricians don't work on pools.

Your photo shows improper wiring and you said hemicals and chlorine are stored in the same room - not good.

Call an electrician and fix the wiring. The rust on (and inside) breakers can interfere with proper operation so plan to replace them. Ask the electrician to evaluate (test) the ground system of the pool to insure it's still functional. If not, fix it.

Move chemicals to a different location where air will not communicate with pool equipment.

Fred,

Thanks. For a new panel, I think I'll spec tin-plated copper bus. The bus on this panel looks fair, but the main lugs are corroded.

I see no sign of grounding on the building or grounding with the cement around the pool. I'll quiz the pool contractor on this. It was put in in 1982, but he's still here.

I believe I'll have to hunt up an electrician that the pool installer trusts.

It look like the pool chemicals will have to find a new home; probably a small plastic contraption from a big-box store. The chlorine has to be destroying the outlets, switches, heater, and motor.

Thanks,

Ted

Two things that are new in the 2009 code about pools are ....1-All pool motors now have to be GFCI protected...and 2-There has to be a 9 sq inch piece of metal installed in the pool water and bonded to the pool bonding conductor. There are now fittings available for this purpose.

What?

(C) Pool Water.

An intentional bond of a minimum conductive
surface area of 5806 mm2 (9 in.2) shall be installed
in contact with the pool water. This bond shall be permitted
to consist of parts that are required to be bonded in

680.26(B).

The first devices were metal plates installed in the back of the skimmers, these are still available, however, most now simply use a piece of metal pipe with an interior square inch dimension which meet the requirements, the metal pipe is bonded to the pool steel and the water flows through the metal pipe, which is inserted between two sections of plastic pipe.

Also allowed is the use of any metallic ladders, handrails, ladder cups,handrail cups, that are in contact with the water and combined total up to or more then 9 sq. inches.

Our AHJ requires it to be a device that is permanent and can not be removed. So far most of what I have seen are skimmers with a metal plate inside and a connection on the outside of the skimmer for the bond wire.

Anyone have such a picture of this plate? I've never seen one.
