What size aluminum wire do I need for 100 amp sub panel?
#2
The cable must have a wire gauge sufficient to the amperage of the subpanel—a 100-amp subpanel requires #4 copper wires or, more commonly, #2 aluminum wires, for example. (Aluminum is often used for feeder cables because the cost is typically much lower than that of copper wires.)
What size wire is good for 60 amps?
6 AWG
For 60 ampere breakers, electricians and professionals suggest using a wire size gauge ranging from 6 AWG to 4 AWG. All household wires have a rating of at least 600V, so only amperage really matters when it comes to determining wire gauge.
What size wire do I need for 50 amps?
6
50 AMP Wire Size For a maximum of 50 amps, you’ll need a wire gauge of 6. Fifty amp breakers are most often used to power many different appliances. However, a kitchen oven can alone require 50 amps. Many electric dryers also require a 50 amp breaker.

How many wires are in a 3/20 wire?
Reading the answer to a different question, a 3/20 wire comprises 3 strands of 20 AWG wire, with each wire capable of carrying a current of 6 A.
What is the current rating of a typical electrical wire?
Typical household wiring is AWG number 12 or 14. Telephone wire is typical AWG 22, 24, or 26. The table below indicates the current ratings of PVC-insulated single and multicore wiring cables. Be aware that the current load depends on installation method – the enclosure – and how well the resistance heat is removed from the cable.
What is the equivalent of 3/20 wire in India?
Generally, in India, for domestic wiring, 3/20 is used for lights and fans, 7/20 for heaters (up to 1.5 KW?) and perhaps 2/10 for the main incomer. Or their equivalent sizes in sq mm.
