My basement has outlets attached to the floor joists (overhead). I would like take off one the wood and swing one down to mount it on the cinder block wall so its easier to get at. Can it be attached directly to the wall or should it be mounted on a board attached to the wall. there is enough wire to bring it down about a foot. An electrical inspector looking at all the wiring so I'd like to do it correctly.
Thanks
Dave

Yes, you can attach it to cinder block. Try and find a hollow part of the cinder block ( they look like a Roman Numeral 3) from above. Blast a 1/2 inch hole and toggle it right to the block. If the block is filled, you can try a tapcon. Use a shorty, the long ones tend to strip out the material and not hold. I'd think maybe a 1" or 1 1/4" will do you.

Just use 1" Tapcon screws or plastic anchors. This way all you need is a 1/4" or 3/16" hole.
You are not hanging a 500lb cabinet.

Bsm't outlet

Hi
Thanks for all the suggestions.. they will help. My only concern now is there any code requirement for a outlet mounted on a masonry wall it will be used for a sump pump. the cord will not reach once the pump in down in the sump hole. I don't believe I I can use an extension cord , here in new jersey anyway!

No extension cords per manufacturer's instructions, every one will say something like:



Also, prohibited in the NEC

Also, a Bad Idea - when I find an extension cord at a sump pump at inspections it's sometimes disconnected or clearly in danger of becoming so.

........

The 2008 NEC eliminated the GFCI exception for sump pumps in unfinished areas of basements, 120V units must now be GFCI protected

Home Inspection: "A business with illogically high liability, slim profit margins and limited economies of scale. An incredibly diverse, multi-disciplined consulting service, delivered under difficult in-field circumstances, before a hostile audience in an impossibly short time frame, requiring the production of an extraordinarily detailed technical report, almost instantly, without benefit of research facilities or resources." - Alan Carson

The sump pump should have it's own cord and plug. You can order/buy them with varying cord lengths. Just put the receptacle where it will reach. You can leave the original receptacle where it is, then branch out and install a new box and device. This will need to be on a GFCI protected circuit.
There is no issue mounting boxes to cinder block or concrete walls. It is done all the time. As mentioned above, simple concrete screws or screws and anchors will make for a solid install. I prefer the concrete screw.
No extension cord allowed. Extension cords are only allowed for temporary/limited use.

The tapcons are great. If you get the kit, you get the drill bit with the screws.

You may want to consider running a dedicated branch for the sump pump, since its failure due to something else tripping the breaker could be a big problem.

Absolutely no extension cords!
