Liability & responsibility of electrician?

And what is your definition of a line cord?

You've never seen 3 Wire with ground, plugs connected to cords on electrical equipment?

No, actually, the equipment most likely had cords on it that already had proper plugs that were properly labeled on the twist locks them self's..

You see, these little details are not coming to light here, did the electrician hard wire the CNC to the service or did he simply supply a compatible source for the mating plug on the cord attached to the CNC ?

I don't know about a lot of other shops how ever, where we work, all of our machine shop equipment have twist lock plugs with cords on them and those that know anything about this, know that they can only be inserted in the proper receptacle.

In short, different service voltages have specified keyed plugs. If the CNC already had a plug connected to it, then the data required by the electrician is on the plug.. and that is as far as the electrician needs to go with that.

If an incorrect plug is in use that does not match the voltage of the equipment but may have been used in an area where voltage was upgraded and receptacles were not changed, then it's the fault of the shop owner for not spending the cash to correct that.

While a router is not as glamorous as a lathe or mill, I do believe they are still considered a machine. Controlled via CNC makes them a CNC machine...

And yes, many of them have cords with plugs. Need pictures?

it's most likely the feed to the building is 480/460 and a transformer is being used. I don't know to many electric companies that will supply 240 3 phase any more.

I'd be willing to bet that the transformer came along with the move and that being the case, yes, it can sag abit when other equipment get going because I can't picture a huge xformer in use here.

He must not get out much....shrug.

And in most of California..that means far far different requirements ..legally.. than does hardwiring.

You are in the dark boy..

Our company hires licensed Electricians for basic things when our electrical staff are to busy to perform the job, we have 3 different businesses we use and each one of them do more illegal hack work than you can even imagine. Many times they return to rework after close inspection from the trade associates.

We have some unlicensed electricians that work for us that I put more confidence in than licensed contractors we hire.

We do not allow any contracted electricians to touch our industrial machines.!!!!!!!! out of the 3 businesses we use, none of them have the skill set required. We do have specialist constructors that know the industrial electronics, perform major over hauls and machine installments that work with our guys. Those are the only ones that are allowed to go past an outlet on a wall. And even then, they have some guys that are not licensed but are very qualified.

Knowledge and the willingness to do it correctly is what matters.

Simply speaking, having a license means that you had to know something or some one to get it, and the local government can collect taxes from the licensed workers. The rest is just fill in for the public to justify the need for a license.

If Licenses were only used to signify the qualification of a persons trade, then you'd see a lot fewer licensed electricians out there.

Diego eh? I know a bunch of ex miltiary guys retired down there, might be talked into taking an asshole out to the desert and burying him so only his head is above ground, then driving home and never going back.

Ill check into it and see if we can ID this guy.

Thanks!

I guess you don't get out much. A laptop is standard issue for setting up some of the HVAC equipment I deal with. Several VFD's per air handler is common plus computer controls to run it all. One of the last air handlers I set up had 7 VFD's, somewhere around

15 electric motors, and was 16 feet wide, by 12 feet high, and 32 feet long. One after that was a bit less complex, a bit larger, and cost $175,000. Needless to say, I don't do residential!

But, the typical electrician looks at the rating plate, pulls the appropriate wire, then walks away from the equipment. Someone else sets it up. Same when I worked at a CNC shop years back. The machine was delivered, set in place, the electrician ran the wires, and then someone else showed up to set up the machine. The sparky that ran the wires had no clue about the machine, he was there just to run the wires. Greg

Have you considered that it is very possible to run the wire to the equipment all to local code, NEC most likely, but the machine itself was not setup to accept what was run to it?? I have equipment in may garage that will run on 208 volt or 240 volt single phase and requires a jumper in the machine to be placed properly depending on what the incoming power is. A sparky could easily run the proper wiring, rated for the voltage and amp draw then walk away. It would be up to me to ensure the jumpers were proper for the supplied voltage. I see this on a daily basis on the job. I would not trust the average electrician to make sure the machine was set up properly! Greg

Ayup..and if you put a plug and cord on a CNC machine..it too is "temporary" and doesnt require a license to do.

Let the Record show that Gunner Asch on or about Sun, 05 Jul 2009 13:41:29 -0700 did write/type or cause to appear in rec.crafts.metalworking the following:

Electricity is like water: if it 'flows' in, it has to 'flow' out. Unlike water, though, it will take short cuts "out of the pipe".

That it always has. Even if you have the blessing of the Treasury Wizards.

You can get a license without being in the union.

Excuses do not make you qualified. Especially if the tests you took were way back in '74.

Of course I can. And did.

Where did you get that date from? Was that the year you were spawned?

I put my C7-C10 on "Hold" with the California BCA in 1998. I think its expired now..as I recall, it only had a 10 yr life on hold.

Shrug..another weekend at a Contractors Fast Learn and take the test on Monday. Not a big deal. Except the fees and costs. Which means Ill simply continue on as a CNC tech who occasionally does electrical work, until the economy turns around. Of course..I may be near retirement age by that time...assuming the US doesnt melt down totally.

Shrug

A little printer that cuts out stickers is technically a "CNC Machine" as well.

The term usually refers to much larger load devices, not your Sears sign router. Also, a good hint was that he had to have wiring ran for it.
