Over Heating Residential Main Panel

Original Residential Electrical Main Breaker 
  
Piggy Back Breaker

Circuit breakers are designed to trip at a given amp rating, the more amps pulled the warmer the breaker becomes factors, wire placement can effect the heat factor, Taking one single pole breaker and making it two (piggy back breakers) also increases heat factor to the bussbar. And is there proper grounding for breakers to operate shortest path to ground theories? 

Usually this is what we have to work with concerning auto start generators, wind & solar inverters grid tied attachments and transfers of voltages from grid to other sources. A full panel of wires that unless tone generated for locations and opening amounts are unknown? 

Electrical power are building blocks of wattage loads it's all in the numbers it takes to run the device whether original or adding on. 

Numbers never lie concerning electrical power

wattage / voltage = amps
amps X voltage = wattage
100/amp Main Breaker is  24000 watts
200/amp Main Breaker is 48000 watts

This is the MAIN BREAKER starting point of this breaker to buss bar protection meaning that this breaker will trip when the heat generated from operation knocks it out aka trips or dead short to ground if correctly system grounding is in place?  A circuit breaker design is to restrict the amount of electrical power this is a heat factor. The main breaker will only take so much before tripping from the many other breakers (heat factors) feeding power to the the home wiring cables. For heat factors it is better to operate 80% load leaving 20% for reserve cooling. By properly placing cables and step down breaker placement a type of heat sink is formed. 

The best fix here is to

(1) add a sub panel main lug next to Residential original  electrical main breaker panel

(2) removing piggy back romex cables from main breaker panel location to sub panel location to free buss bar space in main location
(3) Rearrange main breaker original wiring into step down highest 240/volt amp on down the buss bar
(4) add 1-new ?/amp  breaker into main breaker panel  (aka feed sub panel)   
(5 ) Add new devices as required to wattage loads. If that means updating older your utility meter amp ratings then do it right by raising amp ratings at least double. example 100/amp to 200/amp or 200/amp to 400/amp. The heat factors involved with  this type of step down is the most efficient possible. 

Any electrical power device will operate more efficiently if it's correctly designed ratings are allowed as efficiently as possible. By cramming wiring harness and placing breakers any which way onto the buss bar generates more heat is being generated than is necessary. Reading above Heat Sink will lower heat factors for these types of repairs.
