Can I solder two different gauge wires together?

Sure it is possible. But if you have a powerful enough soldering iron / gun, you should be able to solder the battery wires to the connector if it is the proper connector for your application. Just make sure that you get a real good solder connection – and be very careful not to short anything while soldering.

How do you solder two stranded wires?


  1. Prepare the Wire. Tinning must be done on bare wire. …
  2. Prepare the Soldering Iron. Plug in and turn on the soldering iron, and let it heat up. …
  3. Apply Solder to the Wire. Extend the solder from its spool in a straight line. …
  4. Let the Wire Cool. Let the solder cool, then inspect the results.

How do you join two different wire sizes?

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 mix wire gauges?

You should not mix gauges of wires in the same circuit.

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.

What is the proper way to solder wires?

Touch the heated tip of the soldering gun to the wire joint. Hold the tip firmly in place for a few seconds to heat up the wire. Touch the exposed end of solder lightly to the wire joint. The heat should cause the solder to instantly melt and draw into the meshed strands.

Do you twist wires before soldering?

You want to be able to see if your solder joint is reliable before you close the casing or connector housing. What I want to see, is that the lead goes into the wire, between the strands, not just onto it. If you twist the wires, the strands are often too tight for the lead to flow between them. So don’t twist.

Should I tin stranded wire?

The reasoning behind not tinning the wire is, if the wire is tinned, when the screw closes down on the wire, it would break the solder joint and leave an opening within the strands, which can be susceptible to vibration, loosening and corrosion. By not tinning the wire, you can get a better gas tight joint.

Can you mix 10 gauge and 12 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 you mix 12g and 14g wire?

There is nothing against code mixing wire size for these circuits as long as the OCPD matches the smallest wire. We ask them to mark the wires with tags in the panel so that in the future and for final inspection, we know what is what.

Do wire gauges have to match?

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.

Can you connect 18 gauge wire to 16 gauge?

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

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.

What happens if you use the wrong gauge wire?

Using a wrong wire gauge leads to heat resistance, which can quickly turn into a fire hazard. Notably, each cable is designed to accommodate a specific amount of voltage ideal for a given application. If you use an inappropriately sized wire, it may end up melting due to the high amounts of flowing current.

Why is wire sizing important?

The smaller the wire diameter, the higher the resistance there will be to the flow of energy. When you have high resistance, you generate heat that can turn into a fire hazard. Proper wire size is important for any electrical wire installation. The wire size represents the diameter of the wire conductor.

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

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

Does gauge of wire matter?

Unfortunately, size does matter. The most basic explanation on why wire gauge matters is because the thinner a wire is (higher gauge) the more resistance there will be to the flow of current. More resistance means more energy loss, which means weaker/less reliable detections.

Is AWG wire solid or stranded?

Smaller electrical wire sizes are generally made of solid conductors while wires larger than Number 6 AWG are generally stranded.

Why are wire gauges backwards?

What Wire Gauge Sizes Affect. Beyond international standards, another source of confusion is why wire gauge sizes appear to be backwards of what they should be—as the physical width of the gauge increases the numerical value assigned to it decreases. The explanation goes back to the original process of wire drawing.
