I'm having an electrician wire a lamppost in the backyard. His initial proposal was to do something like this picture shows:
(The diagram is from this article.) The conduit's rise from the ground and entry to the house would be in a prominent place and would be an eyesore, not to mention difficult to install a paver patio around.
I suggested that since the house is on a crawlspace, the conduit could go straight through a hole in the foundation and into the crawlspace. The hole would of course be sealed somehow to keep moisture and critters out of the crawlspace.
It seems that drilling a hole through the foundation is not to be undertaken lightly. So other than the extra work it requires, are there other disadvantages to taking the conduit straight into the crawlspace below-grade?
Note that the house is clad in brick so a hole through masonry will be required either way.
