Do I get a second interview?
Santacruzer's:
To bend a 10" offset using 45 degree bends on 1 1/4" EMT, how far apart do you put your marks on the conduit?
Not a clue.

What is the voltage on 480 Delta? (phase to phase and phase to ground)
Not a clue.

It seems to me that logically, 480/277 is a wye style voltage, so I would bluff on the test and state that the voltage to ground is "240". However, I've never heard a soul speak about a 240/480 system, so I'd probably assume someone (you or me) goofed, and scribble that out and write "277."

What color is the ungrounded conductor? Gray, Green, White or Pink.
Pink.

If you can't answer these questions off the top of your head, you have no business being on a service truck.

That hurts. :D

Marc's:
I generally have them bend some 3/4 emt over an obstruction and draw a start-stop circuit. That sorts em out enough for me.

Nuts.

Well, I guess that renders me unemployable at a commercial or service shop! :D

Re: Pre Hire Test

Some California law....

(b) "Employment" includes the carrying on of any trade,
enterprise, project, industry, business, occupation, or work,
including all excavation, demolition, and construction work, or any
process or operation in any way related thereto, in which any person
is engaged or permitted to work for hire, except household domestic
service.

6304.1. (a) "Employee" means every person who is required or
directed by any employer to engage in any employment or to go to work
or be at any time in any place of employment.

From a NOLO article... Interesting...NOLO - Pre Employment testing
Skills tests range from something as simple as a typing test to something as complicated as an architectural drafting test. Generally speaking, these tests are legal, so long as they genuinely test a skill necessary for the performance of a job.

Interesting story, e57. But I would caution anyone against using hidden cameras as part of a test, or part of your normal business security practices, unless you know how to do it legally. I don't know the legalities of it all, but I suspect there is a requirement related to posting a notice to the effect that you have security cameras in use.

Would it be any more legal if you peeped through a peep hole while the person was bending the pipe? I don't think so. There's no expectation of privacy when you're taking a test. Taking a leak, yes. Trying on clothes at the store, yes. Taking a pipe bending test, no.

The difference is that peeping through a peep hole does not produce a permanent record of the event. You get to observe the event, but you don't get to show the event to others. It's a privacy thing, in the sense that the person being watched has no way of knowing to whom, or when, or under what circumstances the film will be shown.

Not a bad guess, just a wrong answer. But then, I had no clue on most of the questions you answered.

A 480 delta has 480 volts phase to phase. But the voltage from any phase to ground is not knowable, from the information given. If it is a "corner grounded delta," then the voltage from the "corner" to ground is zero, and the voltage from either of the other two phases to ground is 480. If it is an ungrounded delta, the voltage from any phase to ground can be anything whatsoever, and it can vary from moment to moment. Finally, if it is a "high leg delta," you will have to ask someone else. I need another cup of coffee this morning to work that out.
 
Re: Pre Hire Test

The answer should be 480. If it is a corner grounded system both voltages will be 480 and if it is an ungrounded system, the NEC says, both voltages are also 480.
Voltage to Ground. For grounded circuits, the voltage between the given conductor and that point or conductor of the circuit that is grounded; for ungrounded circuits, the greatest voltage between the given conductor and any other conductor of the circuit.

Re: Pre Hire Test

Any ungrounded delta system will have an unrelyable voltage phase to ground. I know this from experience.

I have never come across a 480 volt center ground system. I suppose some math that I am not awake enough to do right now could tell us the voltages.

Thanks to everyone for your help. Keep it comming, I am makeing notes and writing a test as we chat.

As for cameras and peep holes, no worries. If i give one, I am gonna stay in the room so that the applicants can hear me laugh and become more nervous. :p
 
Re: Pre Hire Test

Here is a test from around here.

1 Do you have a drivers licenses?
2 do you have a way to work?
3 do you have some hand tools?

2 out of 3 start monday.
:D
We don't bend much pipe in residentially but we should keep applications a the top of a 20' ext. ladder. and tell them to go get one and fill it out.

What do others wear when applying for an electrical job?

I once read an article in a publication by Robert Half assoc. They said that when applying for a job one should wear clothing that is appropriate for the job for which one is applying. An electrician should wear workboots and jeans, if that is what he expects to be working in.

If someone were applying for a job as an estimator, or project manager, I could see them wearing more dressy cloths.
 
Re: Pre Hire Test

:p Well Im from S. Carolina.... I knew the 480 question but as far as bending conduit.... Id like to know the answer to that one. Is the offset 10" long or 10" high?
Anyway when I got my first job all I was asked was
"So you interested in learnin lectrical?"

One hopes so but I doubt it.

Cameras are everywhere and I doubt we can 'expect privacy' in to many locations.

I certainly do not expect privacy when I go into someones buildings to work. I may be working for a client that has no cameras but I may walk through the lobby of the office building and be recorded.

An employer can 'spy' on their employees in many ways without the employee knowing about it.

They can record video or audio, they can listen to your phone calls (until it becomes clearly a personal call), read any of your emails, listen to your voice mail etc that are done on the companies system.

Nextels can secretly be used as 'employee location devices' via GPS if the employer opts for that service from Nextel.
Some Info

If any or part of that extends to a job applicant I do not know.

I personally do not have an 'expectation of privacy' anywhere but my own home....and even then there are the children. :D
 
Re: Pre Hire Test

Good Ideas for a pre-employment test, we had a ten question test, here's a few:

How many #12's can you (legally) put under a yellow wire nut?

How much take up does a 1/2" emt 90 require?

What voltage would you expect to find in a junction box containing brown,orange&yellow wires?

If you see a receptacle box with a black,red, white & bare wire, what would you do different when trimming this receptacle?

Depends on what brand yellow wire nut

Depends on what brand and style bender you're using. Using an Appleton bender, everything you thought you knew just went out the window.

I'd expect 480. I wouldn't count on anything.

Perhaps break out in a chorus line? If it was a switched receptacle, I might also break out the tab. I might also think that this was where a multi wire circuit branches off two ways, and nut one cable to the black, and one to the red. Depends on who ruffed it, and what room I was in.
 
Re: Pre Hire Test

"If you see a receptacle box with a black,red, white & bare wire, what would you do different when trimming this receptacle?
"


Do the wires continue thru? Are you doing half hots? I am assuming you are refer to the code reference that says if you have 2 circuits with shared nuetral thru a receptacle you have to pigtail the nuetral you can't use the yoke on the receptacle?
 
Re: Pre Hire Test

The written test (Actualy multiple choice) that the guy I mentioned earlier gave had this question: What are the voltages for Black, red, blue, and Brown, orange, yellow?

I answered, but wrote in the margin, that code only required specific color marking of high-leg, grounds and neutrals. He was impressed by that.

(Later I found out one more.... ;) )
 
Re: Pre Hire Test

I once took a pre-hire test were I ended answering almost ever question with a question.

It was not multiple choice.

One of the questioins was: What is a hicky? I asked "the bender or the box support"?

Another was "What is the take up for a 90 deg bend?" no conduit size was even given. so I listed the first three for a greenlee bender.

I cant remeber many of the questions but none of them gave enough information for a simple answer. The employer must not have been impressed, cause I didnt get hired.
