What size wire do I need for 145 amp service
minimum copper conductor for service entrance
145A? Gettin fancy eh? 2/O should feed your needs nicely...Congrats! Chin and I are the resident sparky's around here...We "actually"work with voltage...
Using a 60 degree rating,2/0 copper is the proper size.
For a 145 amp service, you need to use a 2/0 copper size wire. The size wire will be able to contain the service effectively in a 60 degree rating.
