A household clothes dryer needs 30A and electric range needs 40A what are the wires gauges required..

Dryer = #10/3
Range = #8/3

If you pull individual conductors instead of cables then you must make sure that you include a ground wire.

More homework? :rolleyes:

Thank you, but you have to figure out the drop of voltage, the resistance, power etc.
How you give me an answer easy?

LOL...

Don , you must have broken your crystal ball to not know you missed a bunch of answers. Just like teenagers, give them the right answers and your still wrong.

Must be liberal, you give and give and they want more, easy.

Thank you, but I get it the correct answer

Freeboy,

Did I miss something in your question? You only asked for the wire gauge.

I can supply more information if you provide more information.

For example, how can I calculate whether there is a voltage drop condition if you don't supply me with the distances from the main panel to the devices? I'm not clairvoyant.

This is funny.

Maybe the wording of the answer is wrong. Maybe it should be "typically one would use... in a typical houshold installation, but a LOT of info is missing.

Voltage - assume 240
Wire 3 or 4 wire (Do 4 wire at 240 V)
Wire type - assumption copper
Wire length - remember to double it when doing calcs.
Wire type - assume Romex
Wire method - assume no conduit
Amperage - probably wrong anyway. The dryer probably suggests a 40 A circuit, but the dryer could pul. 36.999999 Amps

All of the details are missing. Seasoned professional make some assumptions.

And BTW, the service panel is not in the garage where the cable must be installed underground and 300' away.

Details.
