The feeder wires from the main are connected directly to the top lugs with no disconnect breaker or anything....

Correct...The sub has no disconnect sir....

Yes I'm sorry, the building is brand new....the service is new....No ufer...No pipes.... That message you just gave me cleared everything..... Between everyone helping me and this last message from you, this put the Icing on the cake..... I will be back in touch.....Thank you.....

Thank you very much...That clears up the question I was having going through my head.... Thais makes all the sense in the world now.... switch that neutral at the main to the grounding lug and lift the bonding jumper at the sub..... Wow.....I am so grateful for the help, now maybe I won't look...

Yes sir, I've never seen a main panel wired up like this.... When I looked at it I felt something was wrong.... No disconnect.....anywhere.....No Earth Ground...Anywhere....Sub panel Jacked up off of the main lugs with no disconnect between them anywhere......neutral going to the ground, jumped...

Yes sir you are correct...The main I am calling main does not have a connect.... I followed the lines and they lead directly to a meter with no disconnect between them, and also no earth ground.... Yes sir the sub and the feeder wires are both shoved under the lugs together....along with the...

Thank you very much sir....I am responsible for making sure this is safe and functioning properly....The information you gave me was tremendous value..... May I ask one more question....If no Neutral loads are ever connected, should I still fun that (4th.) wire the actual ground from the main...

oh yea, there is absolutely no earth ground in the main panel.... or a fourth wire from the main supporting a ground....

Yes sir..The sub is in the same building....However, the neutral wire from the main panel is connected to the grounding bus in the sub... Then jumped over to the neutral with a jumper wire.... all of the welders are connected to both the neutral bus and the grounding bus through the ground...

I have several guys Monday hoping I get this figured out this weekend, and that's why I'm asking the pro's...

also, there is no earth ground at all in the main panel..."AT ALL"...

Sir, this is my issue with the sub panel.... There is "No" bare wire ground coming from the main.... The actual wire coming from the main "that would be used for fault" , is the actual neutral wire fed from the neutral lug from the main panel.....

Thank you for explaining this to me very simple like that.... 240 volts doesn't use a neutral wire.... I'm learning......Thank you.....

Thank You....Here is my concern...You did say (2) hots & a Ground.... The actual ground is the neutral wire that's been directly connected to the neutral lug on the main panel.... "There is no actual Ground"

Good Morning...They have I believe the same S.E. Cable used to wire the main, I couldn't see the size but I think its 2/0 ...I will send you a pic. a.s.a.p. Monday afternoon hopefully.....Thank you...

In the sub... not subs....sorry

No sir, the feeder wire is not in a pipe.....and the neutral from the main to the sub is connected to the grounding bus bar.....with a jumper to the neutral bar....then all the welders are connected to both bars in the subs....

That's what I was thinking....Thank you very much for your help..... It's been very helpful.... Oh yea , do I need to have grounding roods in the sub panel when the sub is in the same building, about 30 feet away.... It does have 5 welders...tweco 211i 3in1 ....

This sub panel does not have a ground wire even coming from the main panel....Just 2 hots and a neutral wire that is connected to the grounding bus in the sub ...Then jumped to the grounding bus, and all the welders are grounded to both buses....

The guy wired this shop before I got there has the neutral coming from the main to the sub connected to the grounding bus bar....and there is absolutely no ground coming from the main....all the welders have grounds and they are connected to both grounding bus bar and the neutral bus...
