Hey JMT love your videos. I’m a commercial electrician and work with bx a lot. Bx is wound in a way where it’s easier to pull from one end easier across the ceiling (in this video you pulled the long pull with the opposing direction. Also pulling the long length first and dropping down to your unit with whatever is left on your coil would have been easier. Either way keep up the great work!
You could have just attached the BX to the stat wire at the condenser end and use it as a pull rope to get to the box instead of all the fussing with a fish tape. It would have taken less that a minute and a half to pull that over, and no moving ladders all over the place.
@@sherwinalvarez7365 I’ve seen toggles where the spring had worn out so bad it wouldn’t stay in the up position. I can’t remember seeing many mounted in a normal fashion, the one I found was the one that couldn’t stay “On”. Supermarkets, Commissaries, never seen it. Maybe convenience stores are installed with the switch in the normal orientation, or places with overzealous inspectors.
Putting a relay or contactor on the solenoid circuit to energize it with the thermostat, might work, the coil on the relay has to be rated for 208 volts and the contacts have to be rated 120 volts for the solenoid circuit, to only run when the thermostat energizes the evaporator circuit, just my opinion, I'm sure someone will come up with a negative response, someone always does??? Good job Jumper............
@@johnwalker890 It's not a bad idea at all. The problem is using low voltage tstat wire on anything higher than 24 volts. It is not rated or agency listed for such use and is a serious shock and fire hazard. A relay using tstat wire on 120 or 208, coil or load, is still wrong and a hazard.
Could have installed a 24 volt transformer and relay in the condensing unit and continue to use the low voltage wire. I am about to do the same to shut a cooler condensing unit off while the store is closed for one of my customers.
@@sherwinalvarez7365 Using low voltage wire is most certainly not Code. Low voltage wires' insulation is too thin for high voltage use, and it is, in most cases, not rated for temperatures over 40deg. C ( high voltage wire is 75 or 90 deg C or higher) so even a modest overload will melt low voltage wire. tldr: Never use low voltage wire on 120 or higher regardless of how little current.
@@itsprimetime9865 Oh it will overheat like a toaster element if it shorts or grounds out to the box. Never say never when it comes to electrical stupidity.
@@itsprimetime9865 That makes absolutely no difference! It is fed 208 directly off the incoming power which will be fused/breakered at a minimum of 15 amps which if grounded or shorted out will smoke that wire in no time. The current the contactor coil draws is within what the wire can handle but that was not the issue here.
There would be no need for any wire between the condensing unit and evaporator if he had just installed a 120 volt coil on the solenoid and powered everything from the 115 volt fan circuit. He clearly doesn't understand the proper way to set up a pump down system... He left the solenoid powered on all the time.
Nice work JMT.
You cleaned that mess up real good!

I agree with that one.
Once again , a beautiful thing ... Thx
In refrigeration the switch should always be upside down. Installed that way it can’t vibrate and turn itself off.
Makes sense although I have never seen this in practice or vibrating off.

What makes you best in hvac?
Great video. Thank you for sharing

@@tomoliver8498 Correct........
Nice work Jumper Man. It's amazing what you find out there.
What Camera are you using......Clear picture?
I think GoPro 8
Great job
Good job man
Madness low voltage wire for high voltage well at list it will be fix professionally
Oh? That's not code?

@mxslick50 I was being sarcastic, but thanks all the same. Excellent explanation. Not being sarcastic btw.
Great job 👍
the gauge of the wire shouldn't matter since is cutting off the contactor coil but 18 is a bit Low 14-16 gauge is just fine
It's not the gauge in this case, thermostat wire is NOT rated or sufficiently insulated for 208 volts.
@@mxslick50 thats true But without a Load on the wire it would never over heat but again yeah Thermostat wire is a no no
@@itsprimetime9865 Oh it will overheat like a toaster element if it shorts or grounds out to the box. Never say never when it comes to electrical stupidity.
@@mxslick50 it's on a contactor coil......

Good video.
You didn't need to run the BX just use the 120v to power the tstat and tge solenoid to use the pump down
@@andykuehner2772 You still can't use tstat wire on 120v. Don't be so dense.
