How to Identify a Split Bus Panel

[@heroknaderi]

I appreciate your time. Thanks for sharing. I have one in my house too and I’m planning to add a sub panel for a hot tub.

If you look very closely at the panel label it will usually have an amperage rating. As a rule of thumb these panels were often installed from the mid 1950s until about 1980, they were banned in the 1981 NEC and manufacturers stopped making the panels a year or two later, that said, these were typically used with 100 amp services
