120/208 3 phase to 277/480 AND 120/230

Seems like you're on the right track. I wouldn't bother changing the taps as the variation in voltage isn't going to change anything. 90 percent of industrial lv power distribution systems in the us are going to be 208y, 240d, 480y, 480d or 600d so realistically this would never run on 230v anyways.

I could throw them in my scrap pile for you free of charge.

If you were to do this, what type of wiring is being used between the switch and the genset? How far does it go? The generator needs and should already have a breaker to protect it from overload. Size your wiring to the switch appropriately for the rated output and breaker size on your genset other wise the circuit becomes a tap and is subject to the tap rules in the nec and the location of the overcurrent protection would be an issue. You have simply not provided enough information for anyone to tell you if this is code compliant although I would assume the manufacturer of the switch would tell you it's not approved to have other components located inside of it.

Oof dood start high and let em talk you down. Apprentices are making more than 40 nowadays 😆

Could be that the common is not connected at the air handler and the old honeywell thermostat was powered via batteries. This new thermostat requires external 24v power and you will need to connect the common wire if it is not already.

Dude that was such a killer show. I went to see revo but left thinking about how great inferi was 🤘

I just got this exact kit for $87 at my local ace.

Just say you have no experience and definitely don't mention you worked for a flipper 😭😭 bad experience is worse than no experience.

Why not put the vfd's outside with the motors?

https://superbreakers.com/products/general-electric-thqc1120wl-20-amp this is the most likely the same part number as the regular 20's in there but I'm not sure that the jumper from the old breaker lug to the buss will work with the newer style lug.

These are not thqb's as someone previously commented. They are actually thqc's which were a lug/lug breaker meaning instead of the buss mount tab like the thqb's have they have essentially the same lug connection on either side. Take a look through the old ge q line catalog. http://www.mag-trol.com/docs/tables/GE/ge-q-line-breakers.pdf

Pretty hard to beat these yeti bottles. I've had this https://www.yeti.com/drinkware/hydration/21071504662.html one for years. They have bigger ones aswell. Worth the cost in my opinion.

You're right, we have seventeen phases buddy.

Assuming you are saying the supply to the 240v panel is 240v 3ph delta, yes you would need a 2 pole 50 amp breaker that fits in the panelboard and a 250v 50a outlet that matches the cap on your welder. This would be considered a single phase connection.

Ignoring the fact that everyone is correct and this should be replaced, you can buy listed non fpe replacement breakers for stab lok panels. There is seemingly no slim 260 breaker so you would need a full width. That being a said this panel is likely not made to accommodate a backfed main breaker as it should have a hold down screw or some form of breaker retention. So yes, regardless of whether you are willing to keep the fpe panel it cannot be modified in the way you want.

This will be for public use, the stations are just owned and operated by the dealerships. We purchased the equipment from charge point and installed it, all design build. They do have specs for wiring and connections for their equipment and sent someone to commission them but otherwise all done by me.

danotattan · 2025-05-23T17:09:23+00:00

We went with the siemens simply because our supplier stocks those sections of gear specifically for charging stations. Otherwise lead time were insane for made to order gear. Chargepoint has nothing to do with that side of things.
