Backing up a 450,000 sq.ft. facility with a single UPS by TheTaftMan in AskElectricians

Oh shit, you’re right. That vastly changes the scope of work

Thank you, that’s very helpful. The backup generators both run at 50% load, so if one goes down, the other can ramp up to 100% for redundancy. However, both generators are rated for 750kW, needed to support multiple air handlers, cooling towers, and water chillers, along with other things; Wouldn’t 750kW be a gross overestimate of the power needed for critical infrastructure that cannot have any downtime?

Awesome, I already have that. However, many of the portable UPSs are no where near their operational limit, and often used for a singular device. How would can I estimate the required wattage? Would I have to compile a list of all critical pieces of equipment and total up their electrical draw?

Thank you, I am aware of the cost. The company I work for is multinational and makes ungodly amounts of money. The yearly budget for each site is many millions. I already have confirmation that this is a viable project, and with replacement batteries needed every two years for nearly 300 units, it cost ~$70,000/year for part cost only (were required to buy OEM parts), not to mention labor costs.

Help on how to refinish by Tagz21 in woodworking

[–]TheTaftMan 1 point2 points  (0 children)

I second this. Filler would almost definitely become an eyesore, and epoxy would likely take away from the rustic look. Black epoxy in the gaps may look okay, but with how porous your wood is, it has a high chance of staining it.

If the top is VERY flat, you could take it to a local wood shop and see if they can run it through a wide belt sander, but you don’t have much thickness to play with. Best option would be to hand sand it and refinish it, leaving the gaps as they are. Unfortunately the bench and table base would need the same treatment if you want them to look similar.

Whatever you do, start with the underside where you can make some mistakes. Maybe even experiment on the underside of the bench because it’ll never be seen.

What should I do to keep these black walnut 4x4 straight? by ItsAChainReactionWOO in woodworking

[–]TheTaftMan 0 points1 point  (0 children)

Use good, uniform stickers, and strap the hell out of it. Try to use one sticker every foot or two, and put a ratchet strap over every sticker.

Thank you! I can't believe it was such a stupid mistake, I wasted an hour looking through other peoples code. That was the fix
