Wire Sizes

Aug 12, 2005 7 Replies

Other posters have given you the wire sizes.

What you may not know is that the water heater usually take 3 wires. Where as the dryer and Stove will take 4 wires. Most people use SER cable for these larger loads.

Better check your appliances to be sure.

Greetings,

Where I live people normally use 10 AWG Romex not SER.

Hope this helps, William

Can I get the proper wire sizes for the following:


30A Dryer Outlet
50A Stove Outlet
30A H20 Tank

Thanks,

Using copper

30A= #10 50A= #6

H20 tank may require a #6 separate bare ground wire connected to the water pipe at the heater based on local codes.

Do you really need 50A for the stove?

40A= #8

According to Colbyt :

50A == #6 or #8 depends on precise wire type and length.

#6 will almost always be right, #8 much less so.

30A Dryer Outlet - 10 gage copper 50A Stove Outlet - 6 gage aluminum 30A H20 Tank - 10 gage copper

Hi, To have peace in mind, #8, #6, #8 in order. Tony
