A #4 copper conductor with an insulation factor of 75 or 90 degree C is rated at 110 and 115 amps respectively.
As for the distance this is a voltage drop question and a voltage needs to be stated.
If the run is less than 100' use 4 AWG copper.
10 AWG.
A 30 amp breaker run 75 feet would require you use AWG #10 wire. But, an oven normally pulls more that 30 amps and I would not use #10 wire on a 30 amp breaker for an oven. Normally any newer oven is wired with AWG #6 gauge wire on a 50 amp circuit breaker so the breaker will not trip during heavy use of the oven. Some older ovens could use a #8 wire on a 40 amp breaker.
i just left lowes an they told me to run 100 amp to my building i would need wire size 2-2-2-4 alumninum and run it in conduit the lowes around here does not sell copper wire that size
It depends on the application, but for Single-Phase dwelling service and feeders 3 AWG copper is good for 110 amps. That really equates to 100 amps since you can't get a 110 amp circuit breaker.
If the run is less than 100' use 4 AWG copper.
10 AWG.
Use AWG 12/2 with ground.
Normally older ovens required a AWG #8 wire on a 40 amp breaker. On a modern double oven I would recommend you install AWG #6 on a 50 amp breaker. That way you are safe and will not have to worry about the breaker tripping. It will cost a little more but is worth it in the long run.
I would recommend you use AWG # 2 copper or AWG # 1/0 aluminum for that distance and amperage.
Normally AWG #10 wire on a 30 amp breaker but it really depends on the size of the pump. The pump manufacture will specify the size wire and size breaker needed.

If it is a 110 volt light it can safely run on a 20 amp circuit with AWG # 12 wire.
For a 25 kW furnace, you typically need a 100 amp double-pole circuit breaker. The appropriate wire size would generally be 3 AWG copper or 1 AWG aluminum, depending on the length of the run and local electrical codes. Always consult with a licensed electrician to ensure compliance with local regulations and to confirm the specifications based on your specific installation conditions.
To wire a 100 amp breaker box and safety switch from the power meter, you will need to connect the hot wire from the meter to the main breaker in the breaker box. From there, you will connect the individual circuits to the breakers. The safety switch should be connected after the breaker box to provide an additional level of protection. It's crucial to follow all local building codes and regulations when performing electrical work.
