Not even silicone it's rated 105c |
sounds like high temp pvc |
@Melez right? but apparently SOMEONE must do that, because there is a spec for it.. |
yea. 105 sounds like crosslinked PVC, or some other 'marginally better then the worst plastic we could find' insulation |
I was trying to convince the electrician to hook up 32A EV charger on the 14 awg/ 2.5mm wire that was already there |
@Akbar ... lol. |
https://www.ebay.co.uk/itm/221894009509? |
temperature wasn't the issue, it was the voltage drop |
I’m gonna guess it’s a factory or foundry type thing? Where they’re pulling a lot of amp load often but maybe tie in active cooling is the only way to avoid needing like triple the wire gauge |
@Melez No idea. |
Ok, but tempature also would have been an issue cause its not easy finding 125c+ rated connectors lol |
Inner sheath rated 105c outer sheath rated 70c |
90c underground rating can take 32A here |
What gave me a zinger was the 4.5mm core |
Iv heard of specs allowing you to like, connect a stub of high temp/thicker gauge wire at the end, to heatsink the wire so you can connect it up to 90c things lol |
Voltage sag sucks. It’s crazy how much better heavier gauge wire handles distances. I was looking at running a line to a workshop at 60A, and going up a gauge would drop temps and reduce sag by 15% |
@Melez Voltage sag is all fun and games till you buy a 5HP air compressor. |
Mine would brown out the *house* |
Next up, putting a cpu cooler on your wires |
200A service and I bet it dropped the house voltage to like 60~80% when it kicked in lol |
I’m in the WWing discord too. I brown out my house regularly |
Liquid cooled wires, you just run water through the electrical service conduit for a combined service. |
That was the plan but how do you explain it to the next person who touches the wiring? |
“Btw the part of the cable you can’t see is very thin” |
Same 200A service. My lights all dim when. Heat pump kicks on. I have everything sensitive on UPSs |
this video should do it: |
https://www.reddit.com/r/WTF/comments/wq4ijh/careful_the_water_is_spicy/ |
But yeah the wire I bought is 4.5mm cross section. |
11awg is 4.17mm |
10awg is 5.2mm |
Cause before Anytime the heat pump would kick on my internet would lose sync |
lol |
Should have bought those magical power savers on aliexpress (they’re just capacitors) |
or soft start heat pumps |
… I mean a power conditioner wouldn’t be bad for a stereo. |
might as well fire up my miter saw riight when my compressor starts |
Yeah this one’s older, if/when we replace it I’m definitely going soft start and lower min temp rated. Last winter thing kept needing aux resistive heat |
the new ones are pretty awesome, like -10f/23c at full capacity and soft start doesn't pull more amps than regular load |
I kinda want to get soft starters for all my bigger (2HP+) power tools. Bandsaw and dust collector def don’t wanna start at the same time |
i think it's amazing that there's literally 38 seer heat pumps now |
So since reddit app is being a dick what actually happened to make that sink do that? Everytime I try to go into the comments they close |
Man that would be amazing! I’m in TX and I hate how ridiculous the heat is here |
davidpoz installed one in his shed and it maintains temp using ~100w |
@Rad Nobody really knows, other then most likely the house lost neutral, and/or ground, and is now using the plumbing as ground/neutral. |
God that’s awful |
And that's when I move out and demolition the house |
lol. |
losing neutral is legitimately terrifying |
Probably cheaper than finding out where the fault is |
Shit I need that. I’m hoping to build a workshop on my property sometime in a year or two |
Yea, cause half your house can fry -_-; |
My in-laws house has an outlet with a neutral-ground crossover somewhere |
last house I was in... melted one of the hots outside the house lol. |
Has 25v on the ground. |
-_-; |
I installed a new 240v outlet for my carver friend in his garage |
what LOOKED like a competent electritian had installed the panel |
Normal 125v been hot and neutral but neutral- ground was 25v |
but when I took off the cover, know what I found? |
Oh no |
Neutral bonded to ground at the SUB panel |
Noooo |
and the feed ground was connected to a little aluminum block.. that was screwed onto the panel with a WOOD SCREW |
For those that don't speak electrician? |
same, i am planning on building a 12x14 insulated solar workshed in the next year or two |
I’m fixing up a rental house and the main panel has some neutral-ground fuckery but I should be able to fix it… but what competent electrician |
@Rad SOmeone reused a main panel as a sub panel, and didn't remove the bond wire. so they had the entire garage hooked up to neutral as ground. Meaning if they ever lost neutral, they would have 120v exposed on every one of their woodworking equipment... |
as in, every metal thing in the shop would now be 120v AC |
That’d be pretty dang cool to do like a dedicated solar panel for a heat pump and just.. like set and forget |
Thank you for the nightmare fuel |
also ,the ground that WAS connected... wasn't actually connected to anything, it was just sorta, RESTING against the panel... |
I grabbed some spare wire and connected that ground bar to an actual ground screw on the panel. (your supposed to use a MACHINE screw to screw ground busbars into your panel.. NEVER a wood screw) |
and removed the ground/neutral bridge |
I remember working in an office where the closet I kept my bike in had some fuckery with the grounding and would shock me if I turned the lights on… so I started wearing insulated gloves for that |
Their suing the electrician for that right? @Black Moons |
In addition, due to the poorly connected ground, there panel prob would have caught fire if they ever lost neutral and all that power started backflowing through the shit ground connection |
That’s an accidental death suit in the making |
Nah, I think it was their son who did it lol |
Oh |
Rest of the panel job looked suprisingly good... Other then the circuit that was added by some other idiot later. |
That's when I quietly call the city inspector |
dude put a 30A breaker on 12ga, ziptied the new wires to old wires instead of installing ANY new strain reliefs, and the screws on the 30A breaker where loose. |
They went NC after you pointed that out? |
Man. I don’t fuck around. My in-laws house is jank AF, there was a burning smell whenever they used the dryer… so we cleaned out the dryer (almost fully clogged with lint) still burning smell… then I popped open the subpanel.. the breaker had MELTED and bare connectors were arcing |
Oh, and there was no cover on the double wide, 20A plug box with just a single 240v outlet on it. (the small 240v outlets that you could fit 4 of on a double box) |
hahah. -_-; |
How many wires come from your service head? For my house it’s combined earth and neutral |
Meanwhile, Im still in jail from the time I beat my roommate to death for using a space heater in a 1960's house. No wait I didn't beat them to death.. I wanted to, in the name of safety and self defense though. |
Should be at least 2- your earth is usually bonded to a grounding pole/net/foundation/pipes etc |
Neutral, Ground, Hot, Hot. |
On one of my failed attempts at ebike the wires that were on the controller to the power leads melted |
Also, its normal to have neutral/ground bound at your main panel |
i dunno if they're near you but signature solar runs out of texas and has really cheap setups for that stuff, brand new panels at 50c/w and such |
Yes for me it’s combined neutral/ earth and live |
its against code.. everywhere, AFAIK, to have it bound at a sub-panel |
Don’t get me started on that… back in nyc I rented an apartment with no heat. Space heater on 1 outlet shared with everything else in the room. It started at least 1 small fire. |
@Melez Right? space heaters should be restricted to 1KW at MOST |
Which is why I don't like this |
Oh nice! I’m in TX. I’ll look them up |
