so i think i made a few mistakes installing my sub panel and hoping i can get some help on this.

i had a electrician come over and he gave me the proper underground wire (2 - 2awg and a braided copper around), conduit, 10awg copper ground w/ 10' grounding rod, 24 square d breaker panel, and a 100amp breaker for my main service panel in the house.

picture #1

do i strap it to the conduit to the concrete wall?

Picture #2

Can i just bend the wire up from there and into the panel? or do i have to come straight into the box? if i had to change it and go straight through into the box does it still need strapped?

picture #3

again strapping the conduit to the concrete wall?

picture #4

Where the wire came into the house i made the mistake of stripping off the jacket of the wiring. what can be done about this? where should i run the wire to get it to the box?



i think thats all i haven't done or done right. i have been waiting for 5 weeks now for the electrician to come back and he wont even speak to me so im trying to get as much done as possible. id really like to get this finished so i can start on insulating.

also im in Alberta, canada.

I'd strap it, maybe in the middle of the LB and the ground.
You need another LB inside and put the rest of the wire in conduit all the way into the panel. It needs to be protected the whole way, which means it needs to be in conduit and the conduit needs to be kept from getting damaged.

In the US you would need another full size wire for Neutral but I have no idea what Canadian code requirements are.

I guess you could run the wire inside your house in conduit over to the top of your main panel and enter there.

Strap and secure all conduit.

In the US you would need a seal of some sort around the wires in the conduit under ground.

the electrician told me i was to just run the wire in the basement to the sub panel without any conduit. but now that i have striped the jacket off, is the only way to do this is run conduit?

it seems that running conduit may be kind of hard with only pieces to work with are 90's, lb, couplers, and straight pipe. by code the wire has to on the bottom or sides lower then the main service breaker. water lines are kind of in the way to go straight in the left side

Montea:
If you have a heat gun, like you would use with heat shrink tubing, you can heat the PVC conduit enough to bend it with your bare hands, correction, gloved hands. You will probably want to practice on a scrap piece until you get the hang of it. As you heat the pipe, the surface will turn from flat to glossy, thats when it's ready to bend. A bit too much heat, and it will cause brown spots. Also, watch the outer radius that it doesn't get flat on you.

I don't know what kind of "electrician" your friend is,I would recommend not taking any more advice from him,he is obviously not familiar with the CEC,and definitely not familiar what the accepted practices in the City of Calgary are!
USEB can't be used for feeders to a detached garage...

Fill the conduit with sand and bend it.

It looks like you have a plumber's nightmare in there anyway.

im living in a small town now out in the sticks, it doesnt seem that code apply the same here.

the concrete job is a joke, 36' x 26', 3-4" thick pad, 4 foot pony wall around 2 sides as a retaining wall. The rebar was not lifted up in the pad, 0 pilings, pad has dips in it and water runs to 1 back corner, doors dont seal on the floor because of dips, pony wall was poured ontop of the pad with some rebar sticking up out of the pad, pony wall has no tie backs or anything into the ground, walls are all wavy, 1 4' long wall the forms blew out and is out about 3-4". floor is starting to crack since it has goten cold out. bill for that was $8650 CASH in 20's

all of that and it Passed inspection....

plumbing isnt to bad, theres just so many pipes because the main line comes in there and the water softner and the outside line. i have seen way worse

ok i moved my sub panel so the line comes straight into the box so i dont need a LB fitting.

what type of fastener would work best on the concrete pony wall to anchor the conduit straps to? cement screws?

For some reason,I thought I read Calgary on your first post,it was late...

I wouldn't worry about strapping that conduit to the concrete,it won't go anywhere.
Get some aluminum "flex" armour and connectors for the exposed conductors in the house to the panel.
You need two ground rods,not one,fat chance of driving an eight foot rod or two into the ground at this time of year in Alberta!.Scrap the ground rod idea and throw a ground plate in the ditch,try to get it in the dirt below the frost line,you need #6 insulated ground wire.I would recommend using the correct wiring method-two hots,a neutral and a ground between the two buildings properly sized instead of the "farmer way".You can call Permit Pro,they likely handle electrical inspections in your area and talk to an inspector,they are homeowner friendly and will set you straight,it would be a good idea to grab a permit while you are at it.Its unfortunate that your concrete went bad,lets make sure you get the electrical done right!

Tap-Con's with the apropriate PVC retaier straps.

P.S. I can relate to the codes not applying out where you live. When I built my home 10 years ago (I was the general contractor), I asked the planning and zoning guy with our county, "Who do I contact and at what stages of construction do I need inspections on framing, plumbing and electrical?" His responce was, "I don't have time to make inspections, so if it's good enough for you, it's good enough for me."

LOL. We are building out in sorrento BC and we have only elecrical and septic inspections. We do everything to code plus extra anyways but some of the houses here are a little bit sketchy .

I have seen mobile trailers outside of town where some rednecks just kinda dropped two trailers close together and then connected them together with whatever was lying around. :lol_hitti
