American Wire Guage. The smaller the number the larger the wire. As in an AWG 14/2 wire is much smaller than an AWG 10/2 wire.
American Wire Gauge ( AWG )
Use a wire table to find the cross-section area of #33 wire, multiply by 7, then find the AWG for that cross-section.
AWG 10.
A 100 amp service requires that you use AWG 4 copper wire or AWG 2 aluminum wire.
Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit. 15 amps = AWG # 14 wire with 15 amp breaker 20 amps = AWG # 12 wire with 20 amp breaker 30 amps = AWG # 10 wire with 30 amp breaker 40 amps = AWG # 8 wire with 40 amp breaker
For a 42 amp heater, you would typically need to use a wire size of at least 8 AWG (American Wire Gauge) to ensure the wire can safely handle the current without overheating. It is recommended to consult the National Electrical Code (NEC) or a qualified electrician for specific guidance on wire sizing for your application.
Actually, the amperage rating of the circuit is determined by the size of the wiring.The maximum current capacity of common wire sizes are:#14 AWG: 15 Amps#12 AWG: 20 Amps#10 AWG: 30 AmpsCheck the amp rating of the water heater, and make sure that the wiring that supplies it is the corresponding size. NEVERconnect wire to a breaker set for a higher current than the wire is rated for (for example, do not connect #14 wire to a 20 Amp breaker). Allowing more current in a wire is asking for a fire.The HVAC Veteran
12 AWG wire is larger in diameter than 15 AWG wire. Wire gauge sizes decrease as the number increases, so a lower gauge number represents a larger wire diameter.
The larger the AWG number the smaller the wire. 10 AWG wire can carry more current than 12 AWG wire.The wire sizes of 24 and 26 are the smallest that are used in the electrical.See related links below
Yes, you can wire 16 AWG and 18 AWG wire together, but it’s important to consider the current rating and the specific application. The 16 AWG wire can handle more current than the 18 AWG wire, so ensure that the connection does not exceed the lower rating of the 18 AWG wire. Additionally, make sure that any connectors used are suitable for both wire sizes to ensure a secure and safe connection.

The larger the wire gauge, the smaller the diameter. 12 gauge is bigger than 14 gauge.
American Wire Gauge ( AWG )
Increasing the wire gauge from AWG 22 to AWG 26 will increase the wire's resistance because a higher gauge corresponds to a thinner wire. Thinner wires have higher resistance due to increased electrical resistance per unit length. Therefore, a wire with AWG 26 will have higher resistance compared to a wire with AWG 22.
