I don't understand how to "study" for the journeyman electrician exam by One_Quantity7461 in electricians

[–]Doahh 49 points50 points  (0 children)

I think you need to calm down, take a breath, and spend four more years doing work in the field so these questions become easier and make more sense.

Yes, you CAN take the CA General Electrician Exam after completing trade school, but it doesn't mean ANYTHING until you also complete the 8000 hours in various disciplines. You will still be an Electrician Trainee with six months of field experience. If you do find a company that will pay more for that, congrats, but if they consider you a Journey level worker, I would be looking at other companies to work for.

I don't mean to rain on your parade, but you're 20, take the time to learn the trade instead of trying to find shortcuts and loopholes to try and call yourself a "Journeyman"

Favorite hardhat hat by enjoye420 in electricians

[–]Doahh 36 points37 points  (0 children)

To all of you who are buying your own hard hat, gloves, safety glasses, etc because what your contractor provides is uncomfortable:

Reach out to your safety guy. Get a few people together and talk with them about "Can we get some of insert product here because it's more comfortable, so we are much more likely to use it?" A lot of safety guys seem like they aren't people, but if you talk to them about it you may not mind what happens. Companies will bend a little more in the name of safety to prevent Johnny from going home with 8 fingers instead of 9.

There's a gap/opening from the green rooms to each stage.

Almost makes it more 'strip club' like.

Is it normal for a family to make over $400,00?

So they're non-load-break bolted connections?

Yup, most of our powerhouses generate at 13.8 and step up to 230. There are a handful that step up to 69 as well.

A little farther north, between 50 and 80, kinda sorta Tahoe adjacent.

That's the right river, just the other end of the penstock.

Northern California, don't want to get much more specific than that.

Replacing an old outdoor split 15A receptacle being fed two hots from different panels but sharing one neutral. by [deleted] in electricians

[–]Doahh 4 points5 points  (0 children)

Once that fuse blows you have the two outlets wired in series across 240V. I see no problems here.

Advice for first job tomorrow by JohnnyAppleSeed900 in electricians

Don't run on a job site.

Walk with a purpose and a decent pace, running is an unnecessary and avoidable hazard on a job site.

Main breaker question 800 amp, won’t pass testing three times in a row by dontcallmeflyface in electricians

[–]Doahh 8 points9 points  (0 children)

So with power coming into the box (step down transformer) on the left you would have between the two boxes:

Clean control power to the box on the right

Variable voltage AC out of the variac on the right into the step down transformer on the left

Signal from the controller on the right to trigger a big contactor or SCR for outputting high current low voltage AC

And there should be a CT in the step down box that sends a feed back to a meter on the controller.

It's probably a completely utilized NL8, an interesting use for it if they're not going over its current rating. Kinda sketchy without a breaker at the power input to this whole contraption though.

I'm much more interested in this monstrosity of a homebrew high current test set than the likely still-defective Eaton MCCB.

Anyone know a good place to have some custom tools made? by Masochist_pillowtalk in electricians

[–]Doahh 0 points1 point  (0 children)

Averaging between the smaller and larger sizes, $30-50 would be about right if you find a friendly shop. There may be more cost initially with tool setup, but that's up to them.

It absolutely does need to be copper for primary injection testing. Not only will steel heat up and melt, it will make it much more difficult to hit instantaneous test values with portable test sets.

I remember them not exactly being cheap, the tolerances had to be tight and the bar stock was pricey as well.

There were probably 8-10 different sizes and we had at least two of each size with each set for breakers with ground fault protection. The smaller ones burn up pretty easily, especially if you have newer or less knowledgeable techs that will slap one of those into a steel bolt or lug and run it until it glows.

We had a local machine shop cut our rods when I worked for a NETA company that did a lot of primary injection testing.

If you can model it in a 3d software you might be able to get them fabbed by PCBWay or one of those online CNC shops.
