Depth of grounding rod issue - am in an area where there is 4" of topsoil then about 36" of clay then am faced with the Canadian Shield /rock/ therefore my question is without any ground water of any kind is 36" deep enough for the rod or must I tap into the Shield for a safe ground ?

Ground rods in the US are a minimum of 8 feet long, I assume there is a similar rule in Canada.

here u can drive it at up to a 45degree angle.

IIRC they can run at 45° angle or use the plate or run the rod hortzonal { the latter two you will need to talk the inspector and let them know what the options they can suggest due there is specfic depth they have to set }

Merci.

in case you didnt know, you are gonna want to use a heavy duty hammer drill or small jackhammer to get that rod in the ground. unless you got some popeye arms, and in that case eat some spinach lol

A ground ring could be used, or the ground rod be be put in horizontal. If I reme ber coreectly they have to be buried 30" down.

It doesn't need the "angle thing". It is simply allowed.
