According to desk three hundred.5 of the national electrical code, direct burial nonmetallic raceways not encased in concrete or other raceways is required to have a minimal cover of 18" (450 mm). However, if it's a residential department circuit, a hundred and twenty volts or less, gfci protected, with 20 ampere or less overcurrent protection, it could have a minimal cover of 12".
As fast petey points out, you'll also want a way of disconnect internal or out of doors the constructing near wherein the circuit enters (225.31, 225.32). A method of disconnect is truly any permitted approach of disconnecting all ungrounded conductors. This will be easy snap switches, a pullout disconnect, a safety switch, and so on.
You will deploy a 20 ampere breaker, in the panel within the residence. From there you could both cross immediately into conduit, or you can run some other authorised cable. From the query, it sounds such as you need to apply nonmetallic sheathed cable from the panel, that's just satisfactory. You'll connect the 12/2 with ground nm cable as it should be inside the panel, and run it out to a junction field near wherein the conduit will depart the house.
In case you're not planning on installing an electrical panel inside the storage, the set up is pretty straight forward. You can basically treat the garage circuit, similar to another department circuit. If you do plan on installing a panel within the storage, the subsequent records isn't for you.
So if you're putting in a single branch circuit to deliver the garage, you can installation a gfci breaker and you'll handiest have to bury the conduit 12". In any other case, you'll should bury the conduit 18". Considering the fact that you'll simplest be installing a single or multi-wire branch circuit, you will most effective be required to run an correctly sized grounding conductor along with the present day carrying conductors (250.32(a)ex. 1). You'll enlarge this grounding conductor to every outlet, and join any devices to it. There are no other grounding or bonding necessities, so long as there are not any steel pathways connecting the 2 structures.
