If you’re thinking of buying (or have already purchased) a home that was built between the 1900s and 1950s, it’s important to take note of the home’s wiring and how it will work for you and your electrical needs. As common for older homes, a 200 amp panel was installed on the outside, then a 2" LB under with romex running to the crawl space, no clamps on romex going into LB. I installed a 4x4x18 wireway on the inside back to back with the panel, and then run down into crawl space.

But sometimes an older home grows with additions over the years to 2,000 square feet or more, with air conditioning, electric clothes dryer, range, and dishwasher. The original panel is undersize in both electrical capacity and space inside the box to fit all the wiring.
