I honestly did not know about the ice thickness. Never was much a concern until last year that I overkilled a bit and then a dry n hot streak in the spring and found crazing on my 2 yr old plaster. I dropped the water level about 3 inches below the tile line in anticipation of another round of...

The only concern i have for keeping water level below tile line a lot is the plaster crazing. Not sure if the crazing i had last season had direct correlation with the fact that my concrete was exposed and dry for a couple od weeks later in the spring last year (temperature was higher than now).

I read a few threads and saw different answers, also different pool company gave different numbers too, so want to get some more info here. In Northern VA, so we do get freezing winters here. Company which closed for us indicated 1 inch below skimmer on their invoice (definitely feel they...

And if I go with the hassle of pulling a neutral wire back to the pool panel, is it better to add a neutral bar in the panel for future use? The pool panel box is Eaton BR, so guess this should work Eaton BR and CH 14 Terminal Plug-On Neutral Ground Bar GBKP14CS - The Home Depot

That makes a lot of sense. I recall seeing a thread here where the poster did double GFCI, main panel has one and then at the equipment each has one separate GFCI. Thanks for the insight.

For now, I could not think of any application of 120v from that pool subpanel. My priority of upgrade of current setup would be SWG, VSP, heater in that order, and then maybe landscape lights but that's not really something I care for. You also mentioned that you would not recommend using...

Is it easier to put a 30A GFCI breaker for the pool subpanel feeder line at the main panel side? I feel fishing a separate wire with unknown route (mostly buried in wall, ceiling etc) is more complicated?

That black one goes back to the house side, but there are a few gray ones goes generally towards the back where the garage is. BTW thanks for the info on the knock out seal. Don't even know what it is called, was searching "panel cover".

It feeds to the house basement mostly, and hvac systems

And, I cannot say for sure there are so many wires coming out of the main panel then into the wall, there is one conduit up top (attached pix) that goes up into the wall towards general direction of pool/backyard. The wall where feeder wires comes out is garage cinderblock wall. Another...

To your last comment, I actually have a subpanel next to the main panel, as a matter of fact, in that main panel there ware quite a bit empty/spare breakers that did not connect to anything. So I would need a 30A GFCI if putting it at the main panel side, right?

From the pool panel, I see three feeder wires coming in, white, blue and dark green. Is the dark green ground or neutral? From the 30A breakers at main panel, I see two wires one red one white. The only option for GFCI to work is to fish a separate natural wire from the pool panel back to the...

Thanks a lot. To your best option comment, I don't think I can clearly see the whole run to the pool panel, everything seems to be run inside wall/ceiling. This is where the feeder wire coming out from wall at the pool side.

@ajw22 @BMerrill @Ahultin I've attached the pix of the main panel and the "recommended wiring diagram" on the panel. I think I see the ground bus on the left side, right? And I've read that it was quite common in the days to "bond" Neutral and Ground together at main, so I'm not sure if it is...

Sorry to ask again, about your bolded text here, beg your pardon for my ignorance here, what is the "panel neutral" here, and is it panel dependent (I've seen posts saying the white need to connected to a "Neutral bar" only) or the actual wiring dependent (needs an actual N wire)? For example...

Ah, so no GFCI no surge protector either? Glad I did not pay $100 for that GFCI.

I'm pretty sure it is one of the T100 series mechanic timer, the very basic one where you have to use clips to get the switch turning on/off at certain time.

Very informative discussion, folks, thanks so much. I'm not sure if I have neutral line since this is a 1950s house and the pool was built in the 80s-90s (when the wire was pulled from the main panel). Renovation of the pool did not touch the wiring (from main to sub). The right two breakers...

Thanks a lot for the link. I read a little more about these surge proctors and the location of installation seems to matter a lot. With my picture of my pool subpanel posted above, do you think I have ideal location to install this boltshield? My main panel is far away from the pool subpanel...

I heard about these surge protectors, can you point to a specific model number for the Boltshield and from my subpanel's pix, where should I install it? Thanks a lot.
