Professional electricians recommended the smallest wire size is #6 to #4 AWG.A brief visit to the code indicates that there is a bigger problem, in that the ampacity of 8Ga copper is only 55 at 90C (aluminum 45 Amps) so your wire is too small for a 100 amp service. You need a bare minimum (if everything is rated for 90C) of 3Ga copper or 2Ga aluminum, and probably larger after various derating factors are applied, or if 75C is the limit on any connection.A 150-amp main panel is commonly used as the primary electrical service for residential and small commercial buildings. This capacity is generally adequate to meet the power demands of a typical household or small-scale commercial operation. However, determining what size wire for 150 amp service is crucial. While 1/0 AWG is often recommended ...YES you can use #4 Al as your ground. Your 1AWG Al is good for a 100 AMP feeder (actually 110). From NEC 250.122 this requires an #8 CU or #6 Al ground wire as a minimum (or 6CU and 4 Al if you are really running a 110Amp Feeder). As a reminder, your feeder will be 4 wires, the two hots and the neutral will be #1AL (unless you've de-rated the ...If you’re looking to expand your electrical capacity in your garage, a sub panel is a great solution. A garage sub panel allows you to separate the electrical load from your main p...Allowable ampacity of 3/0 copper wire is 225 Amp, while the allowable ampacity of 4/0 aluminum wire is 205 Amp. 2/0 AWG copper wire is not completely out of the question, but its ampacity is 195 Amp-200 Amp, which will put it at a maximum load, so using 3/0 AWG copper is a better option. For grounding conductors, the minimum size for is 4 AWG ...180. 180. From the above table, if we apply the 83% rule, then the minimum required conductor size must be calculated for 83% of 100 Amps i.e., 83 Amps. So, the 100 Amp Wire Size with an 83% rule is AWG 4 for Copper Conductors and AWG 2 for both Aluminum and Copper-Clad Aluminum Conductors.To calculate the breaker size, simply divide the adjusted wattage by 240 volts to find the rated amperage needed for your subpanel.
