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.
8 AWG.
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
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 is larger.
AWG stands for American Wire Gauge. It is a standardized wire gauging system for the diameters of round, solid, electrically conducting wire.
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
