You never, ever mix wire sizes within a circuit. However you can wire a 30 amp circuit using AWG # 8/3 wire, although that is overkill and AWG #10 wire is what you would normally use on a 30 amp circuit.

Can you splice 18 gauge wire and 12 gauge?
Try it see what happens... >:l Can you splice them? Yes. Should you splice them? No. It really all depends on what your over current protection is. If your #12 wire is on a 20 amp breaker, your #18 wire can melt and cause a fire without tripping the breaker. I do not know what is the amp rating of 18 gauge wire. -- Sparkfighter
Can you mix aluminum wire with romex in a junction box?
No, do not mix aluminum wire with copper wire.
Can you mix two hot wires and neutral in same shut-off switch?
Yes two "hot" wires and a neutral can enter into a switch box. This is done on occasions where a three wire enters a switch box, drops off one circuit for the lighting and the other "hot" wire carries on to feed a receptacle circuit.
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.

Can you connect a 14 gauge extension cord to a 12 gauge extension cord?
Yes, as long as the fuse or circuit breaker is rated for the smallest wire in the circuit, which in this case appears to be the 14 guage. Suppose the 14 guage is rated for 15 amps and the the 12 guage is rated for 20, and there is a 20-amp breaker on the circuit. Now suppose you have a short that draws 18 amps. The 14 guage wire will burn and catch fire, yet the breaker will not trip. That could be dangerous.
Can a 14 gauge wire be used on a GFCI receptacle with a regular 20-amp breaker?
In the USA 14 gauge is only good for 15 amps. It can not be used legally on a circuit that is protected by a 20 amp breaker.It doesn't matter that a GFCI is involved.Several different factors must always be considered when deciding the correct wire size to use:amperage, which is the current to be supplied, measured in amps?length of wire-run?installation situation/site conditions? run inside a conduit?exposed to the air fixed to a wall?extreme heat?damp conditions?underground?To get the right answers refer to the Wiring Codes or Regulations for your locality. (Town/State.)As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Can you mix aluminum wire with romex in a junction box?
No, do not mix aluminum wire with copper wire.
Can a 30 amp fuse replace a 20 amp fuse?
NO!!!! The fuse is your safety device. Never replace a smaller fuse with a larger fuse.Another answerPeople who have done that in the past have burned down their homes. Changing from a 20 amp to 30 amp fuse puts 50% more current through the wire, overheats the wire and can result in fire. Don't do it. As the above post explains, the fuse is your safety device.To Ad:The above answers are dead on. Remember the fuse protects the wiring from overheating and catching on fire. A 20 amp fuse is used on 12 gage wire and a 30 amp fuse is used on 10 gage wire which is must larger. Never mix them up.To Ad: actually if you people wouldve took some kind of electical class its better to put a bigger fuse.. you just do not need to double the size.. if you got a 20 put a 30 in it it want blow.. if you put a 40 then you will have problems...
How many branch circuits can be attached to the screw of a single pole 15 amp breaker?
Your question presumes that each connected wire would be a separate circuit. They are not. However, you may place as many as 2 wires on a breaker, provided they are the same size and both either stranded or solid. Do not mix solid and stranded or different size conductors as this makes it likely that one wire will not be as tight as the other. It is better practice, and in some local jurisdictions is required, to put only one wire on the breaker, run it to a junction box outside the panel, and branch from there. It eliminates confusion and the look of poor workmanship inside the panel, and it meets the requirements of the jurisdictions that do not allow you to do otherwise. <<>> The Canadian electrical code only allows one wire to be connected under the breaker's screw termination. The reasoning for this is that the installer can keep track of the exact amount of devices on the circuit and what section of the home the circuit services. A good reason to keep the breaker to one circuit is when trouble shooting the circuit, two circuits are not disconnected when the breaker is shut off.
Can you mix batteries with differing Amp Hour Ratings?
yes
How do you run an iPod through a guitar or bass amp?
Hopefully, your amp will have a slot marked "MP3". You will need to buy a small connector wire, which you plug into the headphone socket on the iPod at one end and the MP3 socket on the amp at the other. If the socket on the amp is too big, you can get a small connector plug. The master volume control will control the overall volume of the sound that comes out the amplifier, and you can use the volume control on the iPod to decide on the mix.
Can you run 14 gauge wire off 12 wire to a receptical?
No, you can never mix wire sizes in a circuit.

How do you know when you have a good guitar amp?
You know when you have a good guitar amp when it still sounds good cutting through the mix playing live. Many of the solid state amps sound ok on their own, but few can cut it live. Play it loud, in a band, and if it sounds good and distinct in the mix, you have a good amp.
