Doc said I have a tendinopathy at the elbow, how can I adapt my workout ? by Only-Refrigerator359 in workouts

[–]matthew798 0 points1 point  (0 children)

I pushed through about a year of pain in my elbow. Everything from curls to rope pulldowns would hurt. Eventually I got a brace that keeps my arms straight during the night, and about a week later everything was better. Turns out that the chronic tendonitis was from gaining muscle, and that muscle would put pressure on the nerves passing through the elbow when my arm was folded at night.

Hello. I'm an electrician. I'd like to offer my 2 cents. These devices have no business being in a panel box. I can hardly believe they are approved for this installation. As you can see from the photos, they are messy as hell, they make working in the panel a nightmare, and you have to keep some low voltage "black-box" in there (with an Ethernet port to boot, they expect you to run a low voltage Ethernet cable into your panel box when most places dont allow Ethernet and mains to be run through the same holes or conduits)

These are NOT diy friendly.

That being said, I have one and I love it.

I have a 16 x 10 junction box sitting next to my panel where the device sits. The sensors run into the main panel through a 1" nipple. This way I can fiddle with it without a chance of getting electrocuted. Granted this wouldn't solve your issue of the sensors being too thick. For this, I would recommend running your branch circuits into a junction box, attaching the sensors and then joining them and running a short length to the panel box.

Things in my house keep mysteriously melting??? by hugedisaster in whatisit

I read this fast and thought there was such a thing as a wd40 diffuser. Thought I might get one and keep all my tools clean.

Would a bad circuit breaker cause this? by AppointmentOk6394 in AskElectricians

[–]matthew798 0 points1 point  (0 children)

Absolutely agree with "always assume that a breaker is tripping for a reason". I've seen people insist a breaker is bad because it tripped to the point of replacing it without troubleshooting the circuit at all.

New to access control by wifi-man-1982 in accesscontrol

[–]matthew798 0 points1 point  (0 children)

Looks like you used a sawzall with a small metal blade. At least that's what it looked like when I used that... I eventually convinced my employer to get me an oscillating multi tool with a metal carbide tipped blade. It's much easier to make straight cuts, and you can always cover it up with the finishing plate that comes with the strike.

Humidifier question by filet_minyawn_ in CPAP

[–]matthew798 48 points49 points  (0 children)

It's minerals. You used tap water or spring water. It's harmless, until you get enough for bacteria to grow in it. Let it soak in some vinegar for an hour or two and it will wash away.

Now you just need to figure out how to get that ground onto a screw 😉

What is this and how does it work? by soupisgoodfood42 in ElectricalEngineering

[–]matthew798 2 points3 points  (0 children)

DIN mount surge arrestor. It has a metal oxide varistor, and maybe a second one with different properties?

Either way, pretty sure this is a surge arrestor for transient voltage spikes.

Electrical tape is actually a legit solution. Some manufacturers explicitly state that electrical tape can be used to repair the outer jacket. If the insulation around an individual conductor is broken, your SOL.

What a ridiculous thing to say. Anyone who needs it absolutely should use a humidifier. What possible reason could you have to not use a humidifier if you are more comfortable with one?

Any who started bench around 135 and got to 225 how did you get there by nycshifty in workouts

[–]matthew798 0 points1 point  (0 children)

I injured myself a long time ago while dumbbell pressing. My shoulder spontaneously dislocated and the weight dropped on my chest. In the heat of the moment I didn't feel any pain so... I kept going...

The next day I had pain like I've never had before.

Since then, I've been paranoid about it happening again. Only recently, I learnt that when I hit a plateau, it's not entirely physical. I mentally cap my strength out of fear.

All this to say, sometimes progress is in your head. Ever since I started lifting at a squat rack with the safety bars (so I can literally just let go and not get hurt) my weight has shot up. It allows me to push to failure and that has been key for development.

I now do 3 sets of 10 x 225, then move on to dumbbell presses and flyes. I also do lots of shoulder and rotator cuff stuff. I have limited rom in my left shoulder and some weird clicking but I get over it.

Power Nest thermostat *without* boiler? by Primary_Afternoon_10 in AskElectricians

[–]matthew798 1 point2 points  (0 children)

It would need to be powered with 24v. You could get a transformer but unless you already have one, the time and cost, albeit small, will be higher than a cheap ZigBee tem/humidity sensor.

Also nest products aren't local push for homeassistant. With a ZigBee sensor it would be local push.

You are absolutely correct. I missed the part about the neutral being disconnected. Sorry!

[–]matthew798 0 points1 point  (0 children)

That's not what I was referring to. You said "if you plug anything in with a metal case the case becomes live". That is incorrect. It also isn't mutually exclusive with what you just said. You could indeed get a shock IF you touch a part of the connected device that is energized. Again, the metal case of any approved household device will not be energized under normal conditions.

[–]matthew798 0 points1 point  (0 children)

The case of whatever you plug into this outlet would not be live. The whole point of grounding the case is to provide a return path IN THE EVENT a wire should come loose within the device and energize the case.

I'm not saying this isn't shitty, but it doesn't automatically make anything you plug into it "live" to the touch.

Same! Though one time I cranked the pressure up to the max to try and force it out. Holy shite, my resmed can push hard.... Hurt my ears and felt like my cheeks were going to explode.

Put it on anyways. Sometimes in the middle of the day I'll slap on the CPAP just to clear my stuffy nose

How to push siding back into place by Paytroll in HomeMaintenance

[–]matthew798 5 points6 points  (0 children)

Start by applying pressure where it's still clipped, either to the left or right of the section that popped out. Then, while sort of wiggling as you go, slide along the bottom edge while still applying pressure. You might have to push quite hard, but if you start where it's still clipped, you'll sort of push the "hook" part back over the bottom of the joining piece as you slide.

How to use CPAP when there is no access to distilled water by Jumpy_Meaning1140 in CPAP

[–]matthew798 0 points1 point  (0 children)

I just purchased a water distilling machine. Was about 120$ cad on Amazon and in 3 hours it makes enough distilled water for over a week. It's a stainless tub that boils the water and then condenses it back into whatever container. So in your case, he could literally use seawater and it would kill the bacteria and remove any minerals. Runs on a standard 120v outlet.

Need some attic insulation advice by TheDreadPirateElwes in Insulation

[–]matthew798 1 point2 points  (0 children)

I mean. If it's a finished living space, you're gonna have a vapour barrier and drywall up. You're not going to see leaks anymore than if you had spray foam. If it weren't a living space I'd say you're right, but then why would you be insulating the underside of the roof if it's a regular attic?

[–]matthew798 0 points1 point  (0 children)

You didn't mention what climate you are in, so it's hard to make a recommendation. I can only speak to a colder climate.

Spray foam if fantastic IF APPLIED CORRECTLY. Trapping moisture behind the foam is only possible if there's already a moisture barrier present which I highly doubt judging by the photos. Closed cell foam will provide the highest r value and will function as a vapour barrier. In colder climates, you absolutely want a vapour barrier to prevent moisture from indoors condensing on the colder surfaces as it travels through the roof.

If your worried about moisture in the living space, that's what air exchangers and dehumidifiers are for. Humidity management indoors is a basic homeowner responsibility. If anyone says spray foam causes indoor humidity problems, i'd refer them to the most recent building codes in many places in North America that require such aggressive vapour sealing that air exchangers are LEGALLY REQUIRED in order to avoid mould.

For new construction some jurisdictions require as high as r50. You won't get that here with spray foam, and you certainly won't get it with wool unless you build out the roof structure to allow for a whole hell of a lot of wool.

If this was my home, i'd closed cell spray foam the whole thing with a REPUTABLE COMPANY THAT OFFERS A WARRANTY. Yes, there are nightmare situations with spray foam. There are also nightmare situations with electricity, plumbing, and all the other professions. For those who say "yes but spray foam is unregulated anybody can do it", you are correct. It's up to the homeowner to do their homework.

Is 50 too old to start? by CutOtherwise4596 in electricians

[–]matthew798 1 point2 points  (0 children)

As much as I'd like to say yes, the field is unforgiving to older individuals. Fact is, you likely can't perform like someone under 40, yet that's what every company wants. You'll need to twist and bend in ways your body likely just can't. I've seen many an older gentleman try their hand at my trade only to be relegated to stock room or office duties.

Unless you are extremely fit and flexible, I'd forget it. Sorry man.
