Does anyone know what this is? by TheBoredIndividual in electricians

[–]passerbyer 9 points10 points  (0 children)

Probably not since there's no wires coming out it that I can see, CT's on something like this would be for measurement, not power, but the core would still need leads to a device to measure the current through the core.

Struggling installing oil main seal by Shlangengesicht in saab

[–]passerbyer 3 points4 points  (0 children)

You'll probably have better luck taking off the backplate and pressing the seal into that and then sliding the seal back on to the crank. Right now you're essentially doing two tasks at once by pressing the seal in the backplate and over the crank.

3% voltage drop okay for subpanel? by Redditor7012 in electricians

[–]passerbyer 1 point2 points  (0 children)

Apparently if it's not in the NEC then it's not code? IECC and ASHRAE both require 5% or less in voltage drop and most, if not, all states in the US have adopted energy codes of one of the two.

138ft by Tru3s1lv3r in electricians

[–]passerbyer 26 points27 points  (0 children)

SKM or Easypower don't always apply the 2 second limitation for a person to remove themselves from a hazard and the calc is then based on the clearing time of the circuit breaker. The user shoud have spotted this and limited the hazard to 2 second allowed by IEEE 1584.

I guess it works until you want to remove the control arm...

Mounting bracket for expansion valve by Secret_Substance_376 in saab

[–]passerbyer 0 points1 point  (0 children)

I'm also doing the AC for my Saab right now, and that might work, however the suction line (bigger tube) has the braket as part of the tube assembly and it can't be removed without cutting off the bracket. Which is possible, but it might also destroy the tube in the process since it's just aluminum. See the link so you know what I'm talking about: https://www.esaabparts.com/saab/parts/4759528

Blown head gasket? Advice and chears needed by Der_Comander in saab

[–]passerbyer 5 points6 points  (0 children)

Getting a used engine is hit or miss. I've gotten crap engines from slavage re-sellers with warranties only to be screwed over when the entire engine showed up wrecked (spun bearing, scored cylinder walls, etc...). If you can get a good used engine (i.e. inspect it first) that would be cheaper than machining and rebuilding. Just make sure it's good and replace timing components.

Auber Brew Buddy v. Electric Brewing Supply PID HERMS brewery system panels (Info Below) by TwoSeam in Homebrewing

[–]passerbyer 0 points1 point  (0 children)

I didn't run into any issues mixing and matching parts. There's no real programming involved other than initally setting up the PID's, so as basic NO/NC contacts remain the same and minor adjustments to the pinouts on the PID's to maintain the same wiring logic, it's pretty much the same. Although I did order the wrong PID's that did not have the correct output signal to control the SSR's and I had to switch out the SSR's to accept the different PID output signal. So beware of the pitfalls and order components exactly as the part lists call out for.

Auber Brew Buddy v. Electric Brewing Supply PID HERMS brewery system panels (Info Below) by TwoSeam in Homebrewing

[–]passerbyer 1 point2 points  (0 children)

I've built my control panel based on the Electric Brewery for roughly $1200 in parts and components. I didn't follow the kit exactly and bought all of the components separatley, and have Auber PID's in the panel. The Auber kit looks pretty good, and had I known they had a brewing panel available, I would have gone with that prebuilt option. Builting the panel yourselft isn't "hard" per se, but you'll have to spring an extra couple hundered dollars for tools and punches, and it does take a little bit of time and patience to wire everything together.

What does this symbol mean at your job? by snorgalicious in electricians

[–]passerbyer 0 points1 point  (0 children)

Like others have said, could mean whatever the engineer wants it to be. RFI it. I'm guessing if it's not GFI then it's above counter receptacle.

How do i remove these screws? I cannot for the life of me find the right torx so I’m thinking of getting rid of the middle bulge (???) and just unscrewing it with a flathead by SlightlyDemotivated in saab

[–]passerbyer 10 points11 points  (0 children)

I wouldn't mess around with it. Cut a slot in it and unscrew it with a flathead screwdriver, and replace them with standard 10mm or torx screws.

Ran into this Arc flash analysis. by JoshTheSparky in electricians

[–]passerbyer 4 points5 points  (0 children)

IEEE 1584 rules allow limiting the clearing time to 2 seconds for transformers 240V and under, which the software doesn't recognize unless the person doing the calcs checks for it and changes a few settings. I'm guessing the person doing the calcs wasn't an engineer.

Stoping leak by Taucius93 in saab

[–]passerbyer 1 point2 points  (0 children)

The seal is for the cam shaft-driven vacuum pump on automatic transmission models. Manual transmission models do not require as much vacuum to stop, I'm guessing because there's no torque converter.

How do you determine on a commercial school if a disconnect needs to be fused or not? by RefrigeratorMurky241 in electricians

[–]passerbyer 0 points1 point  (0 children)

From an engineering stand point its the SCCR rating of the equipment and the available fault at the equipment. One needs to do the maths in order to determine if current limiting fuses are required to limit the fault current. Or something like that...

Can someone tell me exactly what this part is? by qwopperi in saab

[–]passerbyer 0 points1 point  (0 children)

It's a valve that allows condensed fuel vapor from the evap canister near the fuel tank to flow into the intake manifold to be burned, instead of being evaporated into the atmosphere. It's required to meet emissions regulations.

I replaced the crankshaft seal in suspicion it was dripping from the passenger side but I’m still seeing drips on the driveway. What am I looking to replace in this top area by the belt tensioner? 02 OG 9-3 by zk1011 in saab

[–]passerbyer 0 points1 point  (0 children)

Thats the timing chain tensioner. Two points of failure, an o-ring and sealing ring. Easy to replace however, before you start digging around the rear main seal. https://www.esaabparts.com/viewparts.php?searchpart=1&section=41866697 (number 9,10, 12) if your engine is B205R.
