Thanks for the information. Although I'm a consumer, I've learned that I have to be somewhat knowledgeable or this kind of thing happens
First of all .,

I know you mention electrician but to bury that conductor only 6 inches deep that is not the legal way to do this.

A good electrician will stop right there and talk to you to change to proper conductor or UF cable.

In the conduit ( pipe ) the UF cable is allowed but it will be a bear to pull thru the conduit unless it is seriously oversized the most common methold is use the THHN / THWN conductors.

I did catch one part that you say kilns in there so therefore by the code you will defentally need a subpanel in the garage so per the NEC code you can have single MWBC ( Multi Wire Branch Circuit ) or single circuit but nothing more than that as I mention.

For the depth I know this is more than just a standard 20 amp circuit so bury the conduit minum of 18 inches deep or if you have UF then it will kick to 24 inch deep.

I think there is something more going on here with this set up what you have now.

If possible to post the photo then we can able assit you more on this matter.

As you mention the electrician buried 6 inches deep that part there is NO way a good electrician will do this at all ( I am not suprised if unliscensed handyperson done that and not follow the code at all that is typical which I get it pretty often either side of USA or in France )

Merci,
Marc

So happy I insist on having all my buried electrical cable 24" below grade in conduit. So much easier having it out of the way. If the OP probably did not tell the irigation contractor about the feed and it was too shallow I don't understand how they can blame him.
