    Pole building - How much to do spray foam

    Well the kits will run you about 2$ a board foot. Professional install is going to be about that or more. Though if everything is open it's less work for the installers. How high on the walls and are you doing the ceiling as well?

    Wireless charging issue

    Definitely possible if the antenna and charging coils are too close or improperly shielded.

    Best Grease for Yukon Extreme Hardcore U Joints

    Those are different sounds like they're metal on metal with no bearings. The anti-sieze recommendation makes me think they want pretty much all solids for the lube. I'd stick with the anti-sieze of maybe a moly paste.

    It's tax time

    Used TurboTax for the last couple of year but switched to freetaxusa last year. For some reason TurboTax kept deciding I owed like 10k in additional taxes and wanted me to pay 100 bucks to explain how they came up with that number.

    Do gas stations shut off pumps to order fuel ?

    That doesn't sound quite right to me. I worked a gas station when I was in high school and we had a 3 10,000 gallon tanks. Stopping the pumps wouldn't have changed our measurements much at all.

    Difference between black oxide and zinc plated hardware?

    Thread size and strength are separate measurements so there is no reason a manufacturer can't mix and match. Sae grade is measured in PSI Metric class is measured in MPa

    Difference between black oxide and zinc plated hardware?

    Sae strength is in grade Metric strength is class Both the higher the number the stronger the bolt Most Common ones are grade 2, 5, and 8 which are equivalent to 4, 8.8. 10.9. metric 12.9 is also pretty common and stronger than grade 8...

    Difference between black oxide and zinc plated hardware?

    Black oxide has minimal corrosion resistance. It mostly exists to prevent galling and cosmetic reasons. Zinc has a higher corrosion resistance. Cost is just because BO is cheaper to make than electro plating zinc...

    Run central AC unit on generator

    You would hope but not always and even the usually not as good as it could be. Most residential stuff treats power factor as an afterthought if it's addressed at all. That's because in most areas at least in the US charge by the KW father than KVA like most commercial and industrial. KVA is...

    Run central AC unit on generator

    Or overcorrected if its too big for the load. You do actually want something to remove the start cap from the circuit. PTC or relay are the most common.

    Run central AC unit on generator

    Current as in power not current as in amps. Diodes pass alternating current or direct current in one direction. They don't control current as in amps. There aren't any devices that I'm aware that can directly control amperage except as a function of using it for work This confusion is probably...

    Run central AC unit on generator

    That makes sense. This thread is just really getting alot more detailed than the OP really requested. For a soft start though the freq is equal to the line freq the entire time. In the US that's 60Hz. The soft start starts at a lower voltage and then as the motor begins to move faster and faster...

    Run central AC unit on generator

    Did you read the article? That's not how any of this works. Those "diodes" are the thyristor (SCRs) that make up the soft start. They are switches that allow voltage through them. They look similar to diodes because they work in one direction. That's also why they are back to back in pairs. That...

    Any way to "glue" silicone rubber?

    You can use a primer and then a superglue. I've never tried it myself though. https://www.permabond.com/materials_bonded/how-to-bond-silicone/

    Run central AC unit on generator

    Only if you are using a VFD in a soft start role. A basic soft start is based on thyristors and does not act on the frequency.

    Run central AC unit on generator

    Yes the solid state ones do use Thyristors to ramp the voltage up gradually. They do this by controlling the firing angle of the thyristors. combine this with ohms law and you have an easy way to control current. They don't directly act on the current...

    Run central AC unit on generator

    Yes I suppose it depends on how close to the limits the generator is. The generator will still see the full power requirements needed by the compressor to start it just won't be as long. A "large" capacitor for this use is about 300mfd not near enough to make it invisible to the generator...

    How to remove transmission on 2000 Pontiac Montana?

    I'd venture you might want to pick up a shop manual to at least look over before attempting. Probably the entire subframe though.

    Run central AC unit on generator

    So this is actually a bit more complex of a topic and I simplified a bit in my previous post. You can read a few posts at HVAC school here that explain it better than I but be sure to read all 4 posts. It also has pretty graphs. But the basics are this: Hard start: Large capacitor that...

    Run central AC unit on generator

    That's more or less a hard start without the disconnect relay. They don't actually lower the current needed just the amount of time that current is needed for.
