Hey SoCal!

Just got back tuesday from a 6 week field studies class. First 4 weeks were out around Ely, NV and the final two weeks were spent in Iceland. It was an awesome class and was definitely a once in a life time trip.

We have any GTG's coming up? Ive been out of the FTE loop since the Pismo GTG

 

can someone please call mother nature and ask her to turn off the heater.....

 

It's only for a couple more months


Did you get the pool light replaced?

 

not yet, go back and finish Saturday... i was there yesterday and today till about noon 1 o'clock, then got hot and moved onto a different job.

started Wednesday by digging the trench, water jetting under a walkway and laying about 90' of conduit..... then dived into the scarey disaster of rotten bell boxes and rotten non outdoor rated mechanical time clock.. brain was fried for the day so i stopped about 1pm in west hills it was 104* and humid.

i came back today with a clear head and different parts and got cracking. i got the existing conduit circuits and my new pvc conduit set into a two gang box, from there i branched out into the time clock and into a small 4 space panel. now as far as i know they don't make a reciptical sized 2 pole GFCI, so what we do is put in a small 4 space panel. it about the size of a shoebox. from there we put in a 2 pole GFCI breaker and then pick up the time clock and from the time clock we goto the pool motor... that way all is GFCI protected and hopefully keeps you from getting your azz fried in the pool if there is a malfunction.

the breaker aspect is not needed really as the entire circuit is over current protected at the main panel, but it does give us 2 things in one, one being a disconnect for the pool motor in case you have to service it, and two it gives us the 2 pole GFCI protection we need.

so Saturday i will go back and jack hammer out the cement around the old "deck box" and remove it, then dig down to the 1/2" red brass pipe that goes down to the pool light nitch. from there we will put on a 3/4" pvc conduit and go back to a near by fence and install a new above ground pool light junction box which will be 18" above grade and about 24" above water level. reason being for the height is the water will not hydraulic as easily up into a box that is 24" above water level than 6" above level like the deck box is.

its very common for the old deck boxes to fill with water and then fill the old steel rigid conduits with water and rot them out, causing a short and complete replacement of pool light conduit and deletion of the old deck box.

my other pool equipment job i had this afternoon and which i just got home from about an hour ago, was to basically rework all the pool equipment electrical and add GFCI protection for the pool motor and pool light.

so basically i set a 2 gang bell box and put a switch and blank face GFCI to protect the pool light, and obviously a switch to turn the light on and off. then i branched out of the 2 gang bell box to a small 4 space panel and another 20amp GFCI breaker which feeds the 240 volt pool motor and the automatic chlorine/salt monitoring control panel, got that job done 100% but made for a long day.

also insert a lot of running around the valley for parts and such, racking up the miles on the diesel!.... i just wish the AC worked haha all i ask for is a place to escape the heat between jobs!

some day soon ill get to fixing the AC, along with the rest of the laundry list of wrongs lol.

long way to answer your question Steve, but hopefully its a interesting response.... if not its a good sleeping aid

 

While mother nature turns off the heat, maybe we can convince her to pour down 8,000 gallons of water per minute from the skies to offset the water lost at UCLA.

Please watch.

 

Good advice to heed. We get in a rush and forget about safety.

Thx for sharing.

 

Wow. 1400 degrees in 2 minutes. No wonder the tire blew up. Not too mention the 300 psi. LOL.

Jim

 

So what I gather is that a small amount of concentrated heat can start some kind of chain reaction wherein the tire material begins to outgas inside the tire, causing a runaway increase in pressure until the tire fails.

Is that correct? This is something about which I never knew.

Of course, I'm not one to weld on a rim with a mounted tire on it, either! That, in itself, seems kinda' stupid.

Good lesson for all of us, Bill. Thanks for pointing out this little tid-bit of info!

I don't understand the science behind it, which is what makes it so dangerous and important to share. The external heat from that little bit of welding was not enough, in itself, to cause that. Somehow a chain reaction has been started and the tire is generating the heat.

I've seen tire beads set with ether and a cigarette, and nothing like that happened.

 

In the video it mentions that even hot brakes can start this reaction, and the delay has been as much as 22 hours!

This is a truly strange phenomena.

Ban tires, there dangerous!


interesting video....
