We had a problem at the house and I had to unfinish the basement. It's
now just block wall with some kind of paint on it.

The electrical aspect is a mess. The service panel needs to be secured
and nomex running to switches and outlets is hideous. Everything is
just hanging down the wall.

So, my question is, can I drill holes in the block or morter for
concrete anchors to allow the securing of the panel, the mounting of
raceways and new outlet boxes, etc.

I found some nice blue concrete bolts (they call them anchors)
but it's basically just an 1/8th inch diameter bolt that tightens into a
drilled hole. No 1/4 inch hole for an anchor insert needed.

Is it ok to put these holes in my block basement walls?

TIA
