I am installing a 70 amp outdoor box, one 30 amp 220v and two 20 amp 110v breakers for a travel trailer. The meter loop is rated at 125 amp. I am running this service from the meter loop, main box under ground to the 70amp outdoor box. WHAT SIZE WIRE WILL I NEED TO USE, the total run from end to end is 120'.
Thanks in advance for your assistance.
