NO. He cannot.
You can't put 10/3 cable (or NM) inside the conduit.

What gauge should that be for his approx 50 foot run?
1" pvc *should be* able to handle four #4 conductors (that's the max by code)
It'll be a tight pull but with a short run like 50 feet.. tolerble.

#4 in COPPER will also allow you up to 95Amps (at 90C)
spend the extra now

Assuming that with a 40A breaker we are discussing double pole so that it accepts 2 hots? If so that would be great. In that instance, would there be any issue with just using the 50A breaker I already have that isn't in use? Would #8 THWN carry the load from a 50A breaker?


I can easily have the grounding rod installed right outside the wall if need be.


This is sounding more in the wheelhouse of what I can afford so hopefully he will give me similar recommendations when he comes out. Looking at HD I would be at less than $800 to buy everything and he said I can go with him and buy it from his electrical supply company to get his discount. Good to know that it won't require a giant effort to fix this!
If you decide to run #8 to the garage you need a 40 amp double pole breaker installed in the house panel. A 50 amp breaker is for #6.

40 year licensed commercial electrician and I am not going to give you any advice other than to get a qualified electrician to come to you home and do the calculations.

Nobody on this thread can tell you what you need and what it will cost without being there.

Remote free estimates are worthless.

Not here. At least not according to our electrical inspector, which means not here. He required all 20 Amp circuits to be on 12 ga wire. 15 amp circuits can be on either, but 12 ga is a waste of money unless it is a really long run.

Actually it appears the inspector and I were both correct. http://diy.stackexchange.com/questio...-14-gauge-wire This is not a code osource, but you can find it if you need it.

I guess you missed the point of the thread?


I am not asking anyone to perform the calculations. I am asking for advice on what I might be looking to spend so that WHEN the ELECTRICIAN has time to come out I have a ballpark idea of whether or not I can afford the work. I am doing research in advance prior to wasting his time. I have provided the information on everything currently there, and what will be ran on it.


If something glaringly obvious is going to need major rework (like busting up my patio) it isn't worth the effort right now and I would rather know that now than waste his time.




I grew up in the construction industry but I'm not an electrician hence the reason I am researching and asking questions instead of jumping into it blindly.

I've already planned on copper. I know aluminum has been debated and it will technically work but there are some downfalls to using it.

Actually it appears the inspector and I were both correct. wiring - 20 amp breaker with 12 gauge and 14 gauge wire - Home Improvement Stack Exchange This is not a code osource, but you can find it if you need it.

Again you have no idea what you are talking about sorry to be blunt. I never said anything about circuit wire size, i was talking about 15 and 20 amp receptacles both are legal and NEC code compliant to be used on both 15 and 20 amp circuits. The only time a 20 amp receptacle is required is when it's a single outlet on the circuit.

There is nothing wrong with aluminum wiring that is used today. The majority of the electrical grid is aluminum and most homes in the country have aluminum wiring for the service.

And that's where it ends .OUTSIDE the house . Only a fool would use Al wiring inside his home .

Aluminum wiring is not manufactured anymore in sizes for branch circuits. Not because it's dangerous anymore it's just not necessary because we don't have a shortage in copper like we did in the 50s.

Current aluminum alloy is just as safe as copper. If they made alumininum wire for use in homes today i would use it without worry. The modern aluminum alloy is much different today then it was in the 50s.

Your logic that "and that's where it ends OUTSIDE" makes no sense. So if it's dangerous why would the whole electric grid use it and strap it to the side of your house?

p.s. I forgot to add the aluminum service conductors go inside the house into your panel obviously.
