Electrical Question

[Sberry]

Ask some question about larger installs and it often includes inch pipe and it has its place but I manage with 3/4 and 1/2 and simply so much easier and easier to stock for.. My plumber bud calls for the advice the other night while him and his bud are shopping. Convince him and the bud to split a box of ground screws and 100 cable connectors. They are always trying to find one at a time.

Something interesting in its own right is how they keep the modern equipment code compliant over the years. The mvp is all about that.

Inverters now do the work at 1/2 the input, used to require a 50 circuit now is 30 and some were 24 and now 16A actual.
The wires the machine need are now so small they need to limit the ocpd if they are used. On single voltage models they simply upsize the cord to allow them on a larger circuit.

We have seen ao much innovation in recent years a guy is scared to say never. It seems it might have leveled off some recently with the latest round of inverters but a new 211 is only a sliver from being able to run from a 16 cord. I am not sure what the operator might notice till it didnt work, you can tell a bit with tranny but i bet inverters not so much.
. But a tranny 211 even has cord requirements and 25 ft 14 is it. I doubt anyone could make a real argument that a 12 wouldnt help it and its something i actually tested with a 140. I used 50 ft. Wide open 4v drop 50 ft 12 and 8 with 14 as i recall. On my service it was what i could add and keep 115.
the auto 211 manual is kind of interesting, lot of subtle stuff and i only brush thru it. A difference in older single v models is they reduce the ground size requirement with the minimum wire and they make a note that the plug is not to size opcd.
this is a place a little unclear like the 30 max listing is.

[Sberry]

Dispite 30 amp listing they are desogned to run on 50 amp welding ciurcuits provided the wire is bigger than the minimum listed size. While new machines may require less power in the future, they would need another set of special adapters to meet code requirements for short cuircut interuprion.

[Sberry]

It might just cost to much to save any money trying to cheapen the product. It is somewhat similar to buying a car to save gas milage... but this is not a perfect analagy.
But, may be cheaper to use and more reliable to use a bigger wire rather than a fuse.

[Sberry]

At this rate, pretty soon we will need to add a tiny fuse like we do with modern Christmas lights, ha!

Are you done yet? You must be tired! You are the brother I never had. Pis$ing you off is fun!

The OP hasn't been back in 18 days....and someone has posted like 40 times since then

[Sberry]

I give you too much credit. I actually thought quite highly of you. I guess I misjudge.

I have read the manuals and its sort of interesting to note that at 120 they mention that the unit relies on the breaker for protection. They dont specifically word it as short circuit but the units have a thermal similar to a power strip where they protect the wire ahead of it. They dont mention this about the mvp adapter which is really an adapter with 30A breaker.

[Sberry]

I am glad you are having fun. Thank you, glad I could help, its rewarding.

I'd guess the risk of overheat at 120 or 115 volts power is small. I haven't followed much, are we talking about a 20 amp breaker?

[Sberry]

Yes sir. A 20. I think rhe overheat protection is from its own thermal, the breaker is simply short circuit in the case of 120v. Built like a power strip. I guess it is at both voltages.
i am sure you are more leaened on real electric than i am. Its simply curiosity on my part as to how low they can go for service. Looks like maybe they could be able to get to 20A service ay 240 but it would likely add other code complications.

I am kind of facinated with the fireward thinki g by these guys and the code. Despite the huge changes the code changes are rather few and minor and the manf modify the machi es to stay in. I think yhey went thru the dvi stage and then got to the mvp where they figure out how to use smaller cord. The dvi required user install and prolly wasnt a problem with larger conduxtors
i think they might still do this with larger machines but not familiar with them.
