Can you mix different gauges of wire?

The short answer is yes, different gauge wiring can be used on a single circuit.

Can you mix 12 gauge and 14 gauge wire?

Anyway, the first subject is a bit touchy because it makes it difficult to perform an inspection when all of the wires coming into the panel are 12 but many of the circuits have 14 in them too. There is nothing against code mixing wire size for these circuits as long as the OCPD matches the smallest wire.

Can I mix 12 and 10 gauge wire?





You haven’t said how you will manage the transition from 10 gauge to 12 gauge. If you are thinking of wire nuts in a junction box, then the answer is that you cannot do this safely. The 20A breaker’s job is to protect the load wire connected to it. A 12 gauge wire needs a 20A breaker to protect it.

Can I mix 16 and 18 gauge wire?

Yes the 16-gauge will work just fine. Make sure your connections are well insulated.

Can you connect 12 gauge wire to 16 gauge wire?

Strip the 12 gauge wire extra long so it goes all the way through the butt connector with the tip extending just a bit out of the metal barrel. Then insert your 16 gauge wire into the other end so it’s side-by-side with the 12. That’ll give you the build you need for a good crimp.

Can I connect a bigger wire to a smaller wire?

Wire size is usually based upon the current load each is expected to use. As long as you do not draw too much current through the smaller wires you are usually OK.

Can you change Wire Gauge mid run?





You can always use a larger gauge than is required



whatever, as long as your wiring methods are proper. There’s one hitch, but it’s a “practical, implementation” issue moreso than a rule. That’s attaching the wire to the device, receptacle, switch, whatever, or making the larger wire fit somewhere.

What happens if you use 14 gauge wire on a 20 amp circuit?

The answer is NO, see answers below but 14 gauge wiring in the circuit requires a 15 amp breaker. If you spend a few dollars more and use number 12 wire you can use the 20 amp breaker.

Can I use 12 gauge wire on a 15 amp outlet?

Because it has even less chance of overheating, 12-gauge wire is also acceptable on a 15-amp circuit.

Can I double up 14 gauge wire?

Doubling is allowed for much larger sizes. The #14 AWG Romex is not useless, keep it for any circuit that will be protected with 15A fuse. An exception is where the voltage drop is more than 5% ( extra long runs with high load), or exposed to high temperature.

Can you double up wire?



Yes that is an acceptable solution electrically, but 5 separate conductors will weigh more than one single larger conductor of the same total amp rating. It is the same amount of copper, but a lot more insulation.

How do you wire two 12 gauge wires together?

Quote from the video:
Quote from Youtube video: You're going to press them into the connector as shown. And then when you insert the second wire you're actually going to push that wire into the other.

How do you splice different size wires?

Use a butt splice (crimp connector) and make sure the wire is fully inserted. Take the larger gauge wire and slip a piece of heat shrink over it first before crimping it in the butt splice. Crimp both sides and heat shrink.

Can you connect 8 gauge wire 10 gauge?



Yes, if it’s approved for the line voltage and temperature and if connectors (e.g. wire nuts) are sized to fit. A lower gauge number means heavier wire, able to carry more current safely, with lower voltage drop for the same length, so it should be quite safe if fused correctly for 10-gauge.

Can you wire nut 8 gauge wire?

Typically, wires are meant to be twisted together first, before applying the wire nut. The large, blue marrettes are designed to handle a pair of #8 AWG conductors.

How do you connect 6 gauge wire to 8 gauge wire?

Quote from Youtube video: And i'm just going to start very lightly. Not a lot of pressure here very lightly just braiding these two sets of wires.
