run wire through concrete wall

thinking of moving my noisy air compressor outside of my garage to cut down on noise. I would likely use one of those rubbermaid storage sheds to house it near the back of garage. How would I run a wire through concrete block wall? I was thinking drill large hole for condiut and feed the wire through that and insulate around it afterwards. and attach the electrical box to the outside block within the confines of the storage shed w wet location in use cover. Any thoughts? It would be GFCI. Thanks-Josh

Good idea! Sounds like it would work fine. Should cut down on the noise, plus free up some space. How are you piping in the air?

IVe been soldering copper piping to various points in the garage that will then connect to flex lines from the ceiling. I have a main 3 ball valve shut off "manifold" near where the copper line will pass through the concrete wall, inside of a larger 3/4 pvc tube, ill insulate it up with expanding foam once Im sure it all works.

I also think I will put an inline switch ( with led so I know when its on) so that I can turn the compressor on/off from inside the garage, and just leave the compressor switch on. I got this unit from Harbor freight that automatically cycles the drain to blow out condensation so I wont have to go outside and drain it manually.

It will be my best "automation" effort yet! Thanks for the help-Josh

Rewiring for new dryer

G

gregdam on Jul 07, 2003

I'm in the middle of moving my electric dryer from the basement up to it's new location in the first floor bathroom. Here's my question... In the basement, the dryer receptacle is located in a surface mounted brown box, the typical type, with a three prong receptacle. The ground wire is attached to the metal box. In the new location I wanted to flush mount the receptacle is a typical blue plastic electrical box. I obviosly can't ground the ground wire to the plastic box. At the typical box improvement store I saw a four prong flush mounted receptacle. Is this the receptacle that I now should use, the fourth plug for the ground wire? Thanks

Ceiling Fan Installation Problems

J

jwalzer on Jul 02, 2003

Hello All, I spent last night trying to install a ceiling fan in a bedroom in my house. The spot that I am installing the fan in had a light fixture there previously, so no cutting was necessary. However, the junction box for the fixture was not mounted in a way that lead me to believe it could support my new ceiling fan. As a result, I crawled up into the attic and installed a metal brace that I bought, and hung the new junction box from it. The metal brace is basically a metal bar that has a extending screw from one end. Both ends of the brace have feet, that have claws meant to dig into the joists. There are two questions I have: one, the junction box is extremely close to one of the joists, so al the weight of the fan will be supported on one side of the metal brace; is this ok? And two, The fan installation guide says to screw in a 2x4 brace between the joists, and then mount the junction box to that wooden brace; is this necessary, or can I still use the metal brace that I bought? -jw
