How to run a cable underfloor from a wall socket?

Yes, as long as you do not run it under the floor joists. New electrical code requires that you drill a hole through the floor joists and run the wire through those holes. It cannot be hanging under the floor joists. If you see wires are already running under the floor joists then go ahead and run the wire under the joists attaching it on every other joists with a wire staple. Make sure they wire does not make contact with any metal ductwork or any other metal objects. Match the wire with what is already in the wall outlet you are jumping off of. If it is 12/2 then use 12/2, if it is 14/2 then use 14/2. Never mix wire gauges.

Does 6 gauge wire need to be in a conduit if run in a finished garage along the wall and ceiling?

If you are talking about #6 building wire, it needs to have mechanical protection. This means that it has to be run in conduit. If you are talking about #6 cable set like Romex, then it only has to have mechanically protection below a five foot elevation from the garage's finished floor. If the wall that the cable set is running in is going to be finished with drywall or plywood then that is considered protected.


Should solid copper or stranded copper be used with the pressure terminals of a duplex receptacle?

Either one can be used. Electricians prefer to use a solid wire and use the screw terminals rather that the pressure terminals. An eyelet can be formed with solid wire where as using stranded wire takes a bit more preparation to use. The stranded wire has to be wound tighter at the termination end. This is so that when the stranded wire is tightened under the screw terminal the wire does not splay into individual strands some of which do not get under the terminal screw. With some of the strands not tightened under the screw, this is the same as using a smaller size wire. The breaker feeding the receptacle is matched to a specific wire size. The now smaller wire size has a breaker greater than the ampacity of the wire. This could lead to overheating of the wire under full load and eventually cause a breakdown of the insulation. Once the insulation has broken down, the breaker will trip due to a short circuit. This wire will have to be replaced. This could involve opening the wall board to remove the burnt wiring should this happen.Most residential wiring is done with solid copper wire. In industrial applications, stranded THHN wire is used because many wires are run through conduits from service boxes and many different colors and gauges can be run to different locations. I personally would not use stranded in a residential application.

How do you replace the dimmer switch in the steering column with one on the floor?

1. Got to the Public Library and request the Electrical Shop Manual for your year, unless you are able to locate the HI-BEAM wire. 2. Locate the wire that runs from the steering column switch to the C200 connector -- the very large connector the connects the steering column wiring harness to the firewall harness. 3. Either cut this wire and run the FIREWALL end to the new floor switch OR tie into this wire. NOT cutting it allows both column AND floor control. 4. Run the YELLOW wire from the HEAD/PARK Light Switch to the new floor mounted switch -- it's usually from pin 'D'.

What if the floor at the back get really damp it still comes a day after running the AC Now there's a strong odor smells like acetone Does anybody have any idea Lexus ES300?

I can't tell for sure but the ac has a drain that goes through the floor under the dash on the passenger side. this can become clogged and cause the water that is created by the air conditioner to run under the carpet and into the rear floor which is the lowest point. the smell can be caused by meldew. There is a drain tube that is visable under the car hat you can run a small wire up into and clean it out but be careful and don't poke too hard as to damage the coil.
