I am in Texas and Texas requires the meter pole and service entrance components to be done by the customer. I am a first time do it yourselfer who recently joined the shed to house movement. I went to a local hardware store to buy a ring type 125 amp meter (required) and the wires for the weatherhead. Only problem is the attendants at the store were just as clueless as me. Anyway I came out of the store with 1 gauge Cerro copper wire for a 125 amp meter, nonrefundable. After googling I keep seeing 2 awg for 125. Whats the difference? Which is bigger or better? Can I not use what I bought?
