I am installing 2 new porch lights and a flood light for the back porch. The interior walls are open and we are preparing to install the exterior siding. We just selected the type of light fixtures to be installed and are trying to coordinate it with the siding courses. Question: Can I use a regular round box or do I need to install an exterior rated box? The box will be inside the wall. Will a rubber gasket, available at a home center, be enough to protect the wires inside from the elements if I use a reg. round box? I guess this would also apply to the box for the outlets we are planning to install. Thanks

Hi all, first time poster, long time lurker. ;) Just moved into an apartment, so I have limited ability to rewire and/or access the mains to check things out thoroughly. We installed a small window AC unit (6000btu), and had it running as a fan. when we switched it to cooling, it didn't kick in the compressor, but it did start making a different noise. just not the right noise. If it were a car, I'd say it wasn't turning over. When this happens, all the lights on the same circuit go dim. I threw a multimeter on the line to watch what happens, the base voltage is about 116, when I hit the cooling mode, it drops to around 90V. My question is this: is it the unit or the wiring? We've had the AC unit for about 2 years, and just drove it 400 miles in the back of a rental truck, so it's had a bit of abuse, but should still work. It wouldn't be the end of the world to replace it though, but I'd rather not replace it if the same thing is going to happen with the next one. advice please!
