Thanks for the input so far, as mentioned former DC hi-leg/ Delta stuff confuses me and was a surprise when the panel was installed. I want to run the following 240V items, a 15Amp IR compressor, a Miller Map gas welder needing a 50Amp breaker, and a future 20Amp lift. So a 100 Amp 240 volt sub...

The unlabeled circuits are the old unlabeled fuse panel circuits. I need to sort out the loads but typically they are either lighting circuts or power to three or four 120V outlets each circuit. I screwed up on the three phase, it is a 120/208/240 four wire service. It had a rectifier feeding a...

Hello; I need some help with capacity math on a three phase panel "upgrade". I had a electric contractor replace the entire service drop and panel(s) on my garage building. It is three phase service, it was an old printing shop with separate 110V Direct Current in parts, and a 120/240 Volt A/C...

I took two Votech classes years ago, but never practiced again since i did not have a welder (and other parts of life got in the way). Thanks for the help all. Mark

Hi all; I am helping my sister clear out her late husbands equipment and ran into an old Lincoln tombstone, see the photo. It is free to me if I want it. Stored in a garage for probably 20+ years, and the cable ends are pretty chewed up. I understand these are useful tools, but have no idea how...

To answer a question, see the photo here for the "blocked" spaces in the panel, they are the hi leg ones. So, Do I understand correctly that a standard 2 pole breaker will provide 240 Volts? My compressor data plate says 240, so I suspect I need to give it that. Thanks all, Mark

Hello; I recently had an electrical contractor upgrade the panels in my shop building, a former printing plant with three phase service. This powered a few 110V DC cartridge fuse boxes and a separate 110V A/C fuse panel. I had them replace it with a new Siemens 200A three phase panel...

Yes, the HF store said too bad, didn't care. I had four of these holding up a car on a concrete floor in my shop while I removed the transmission (with a trans jack). The broken part was lying on the floor under the jack, I only noticed it when chasing a nut that rolled away. Mark

Three Ton Jack Stands : Fail!! See photo. Just holding up an old Imperial, sort of!

Hi all; I would like an opinion from the electrical experts here. I have a 1930's commercial building in Detroit that is now my garage. It has a couple of 110 volt A/C circuits run with metal conduit, which are mostly buried in the floor concrete. The circuits are two wire, no ground wire, with...

Cool. Thanks all for your input. Mark

Also, for those who wanted to see the inside of the building, a few pictures. Thanks for the advice. Mark

Sorry for the delay in response, I wanted to go to the building and get pictures. The furnace is an electronic ignition, Lenox Pulse unit (no pilot). There are two Schedule 40 pipes for intake and exhaust air, that go to the roof. Also, while the intake on the furnace appears to be on the floor...

The garage is on the east side of Detroit, near I-94. I had the same concern problem with taxes, but you can appeal the assessments to the State (after appealing to the city, a waste of time but a required formality). Apparently, unless it is a foreclosed property, the purchase price carries a...

Hi all; I have a 3200 square foot concrete block building in Detroit, which is my car play pen. It was a printing shop previously, and is an open floor space. It has a high efficiency natural gas furnace forced air with overhead duct-work; the furnace is out in the open space of the building. Is...
