Yes as an employee, but additional certification is required in both provinces to represent or act as a contractor.
One for the Electricians out there

in alberta you need a masters to act as a contractor, in sask and manitoba they call it something different. B.C i have no knowledge

100 KW Back up Gen set okay so it's a bit of over kill for average house ...
But it only has 58 hous on it.....
Kohker 100 RZG standby natural gas Generator
It is complete with auto transfer switch, auto battery charger, 150 KVA transformer.
Have pictures if anyone has an interest...
When it was installed the package was $95,000.00
Want it gone have been asking $20,000 but go ahead make me an offer...

i have plans for a generator like that, but not for a year or two..sorry
depends where it hits you, if it crosses your heart then thats when the damage is done. if it enters your hand and exits your elbow you will live and might be fine or you may have permament nerve damage or loose you arm. more people are injured with low voltage systems like in homes, because they under estimate the potential of electricity.
4500W on one side of the transformer is 4500W on the other side and all it takes is a fraction of a second, a few seconds it a long time in the electricity world
there is enough of a current draw in a 40W bulb to stop the heart at 120V

ok i must be dumb cause a spark plug jolt dosnt kill me, and a criminal cause i use a genset to power my house when the power goes out. And the electricians out there are all at risk cause there are 100s of gensets in most every town. You would think there would be procedures in place so that linemen dont get zapped? Hmm lets think about that...........

I'd say comparing the jolt from a spark plug and that from a 5KW Gen set IS dumb. Spark plug is getting power from a what? 100W stator? Gen set is 50X that. Fact is that it is against the law to hook up a gen set to your house without some sort of interlock. Just because you do it doesn't make it right.....or legal. There are procedures in place to try and ensure that linemen don't get zapped but ch!t happens, not nearly as often though if people follow the rules . Not really sure what your point is.

OK "I'd say comparing the jolt from a spark plug and that from a 5KW Gen set IS dumb." That i deserve. WHy dont these electricians of 15 years explain how that lineman gets killed? What the heck are they up too? They are on a giant fibreglass pogo stick and wrapped in rubber. They service stuff live everyday.........

its current that kills you not voltage.. so a 20000V spark plug is irrelevant!
there is precautions put in place by the supply authority, but they might not assume fred joe and tom have gen sets in place back feading the grid. either way the linesman/electrician should have it stuck in his brain to treat all lines like they are hot, kind of treating all guns like they are loaded. at least thats what I do before touching anything that isn't new construction.

when a 5 kva is transformed to what ever it goes to does the amperage stay the same? Or does it drop in a giagantic fashion?

Ya. It goes by the number of turns or ratio. That's why supply lines are smaller AWG. For example if you have a 20A draw on your secondary and have a turns ratio of 20:1 you will have 1A on your primary.
It is the job of the linesman to do his dodiligance when coming in contact with lines. Sometimes they get complacent. But typically if they are throwing a disconnect on a line they have a hot stick. Rarely do linesman get injured on the job with all the gear they have knowledge they have protocols in place. The whole reason to this argument is so they don't add one more variable into the equation. Ie. Back feeding a transformer that a linesman could be servicing or whatever the case may be. Picture this. Your power goes out so you say WTF and start up the gen set without a proper transfer switch installed. You also forget to throw your main breaker in the off position. Bc hydro is down the street about to disconnect your transformer for replacement. They throw the main disconnect so the transformer is dead. He climbs the pole and goes to disconnect the jumper. You in the meantime started your gen set back feeding when he is unaware are gets electrocuted from the primary side of the transformer and it kills him. That's what we are getting at

What you meant to say is that the output of the transfomer in VA is the determining factor in the output. Turns ratio has to do with induced voltage on the secondary side.
i.e 2000kva tranformer will still put out 2000kva on the secondary side but the rated amperage is a divendend of the root three of the voltage.

Um "post reported" what does that mean. Did i hurt your feelers by asking you to express your point so that we could all understand?

Thank you Mattiac for giving info that makes sense.
ok first off when the power goes out BC Hydro isnt anywhere in the area and wont be for at least an hour. Second as i explained earlier When i didnt shut down the main breaker the genset grunted and threw the overload, letting me know i didnt do something right. Therefore by the time they get there, the line is still dead. Again im not an electrician BUT i am sure that components get isolated before removal! If not i say let Darwins law rule.
If your main breaker is on,your also trying to feed power to the rest of your neighbors.
there are safety precations that we take everyday to do our job, or we wouldnt have these jobs very long.
the safety precations are that we have to grounding on both sides of the main 25kV line so that if the power does come back on it protects the man working in the safe zone. but there is no protection coming from the customers side, as we assume there is no backfeed from houses.
there are crews that work on the line hot and with rubber and sticks, but during lets say a simple transformer change the lineman has to get right up to the transformer and disconnect the connections by hand. and thats where the backfeed will get him

Wow...go away for a couple of days, and the thread goes right sideways 
Lots of good information though, thanks again guys, at least when I go in now, I can make a semi-informed decision. As I said before, I will definitley be getting the proper switch installed (by an electrician) when I do this....I will also remember to never have my foot in a bucket of water while holding a spark plug (or something like that). :d

It's ok as long as it's distilled water, that doesn't conduct electricity. Salt water a big nono:d:d
