The size of the breakers does not provide you with the needed information. You need connected load, name plate data from the equipment connected, clip on amp readings on each phase and any other info you can get.
After accumulation of the information you can make a decicion as to what size equipment you will need. Add 25% for future load. Its possible that the old load has been removed and the present breakers size
is not required
