The frequency has no direct relationship to the size of wire. Wire is sized as to the amount of current a load draws in a circuit.
Not enough information. Lights? Pumps?
many wires are. such as 14-2 Romex. 12-2 Romex. Any THHN wire of any size. This list is very long. If you have a speific application then you need to check the NEC 2005 Table 310.13 Conductor Applications and Insulations.
The breaker size for a TNIA-10 wire depends on the maximum current carrying capacity of the wire, which is typically indicated on the wire's packaging or in its specifications sheet. You should select a breaker that is rated slightly higher than the wire's maximum current capacity to ensure safety and avoid overloading the wire. It is recommended to consult with a qualified electrician for specific guidance on breaker sizing for your installation.
Most lamp wire is parallel #16 conductors.
The wire size is dependent upon the wattage size of your water heater. The higher the wattage the larger the wire size. A standard 3000 watt heater will use a two pole 20 amp breaker connected to 2C #12 wire.
This can not be answered with the information you have given. 60Hz does not relate the the current draw so wire size can not be calculated.
For accommodating 4/3 wire, a 1-inch conduit size should be used.
For a 100 amp service in copper, a wire size of 3/0 AWG should be used.
For a 15 amp circuit, a 14-gauge wire should be used.
A 6-gauge wire should be used with a 60 amp breaker.
For a 25 amp breaker, a wire size of at least 10 gauge should be used to safely handle the current.
For a 30 amp 240 volt circuit, a wire size of 10 AWG should be used.
For a 100 amp breaker, a wire size of 2 AWG (American Wire Gauge) should be used to ensure proper electrical safety and performance.
For a 50 amp breaker, a wire size of at least 6 AWG (American Wire Gauge) should be used to safely handle the electrical load.
For a 50 amp breaker, a wire size of at least 6 AWG (American Wire Gauge) should be used to safely handle the electrical load.
For a 30 amp circuit, a wire size of 10 AWG (American Wire Gauge) should be used to ensure safety and proper electrical conductivity.
For 10/2 wire, a 3/4 inch conduit should be used.
