Sub Panel or Mini Breakers

I currently have 100amp service in my house and I'm out of spaces to add breakers. I need (4) new 20's and a 30 for a 220 line. I was originally thinking of adding a 60amp sub panel. I went to Home Depot and the guy suggested I use mini breakers instead of installing the sub panel. Are these safe? Can I replace all of my 20 amp breakers with these mini breakers and therefore gain more spaces. What do you guys think?

Thanks

The answer depends on whether your panel is designed for mini breakers and whether or not you have exceeded the maximum number of breakers allowed for your panel.

let me re-phrase that.


Where can I find out what the max number of breakers my panel can hold?

Read the information on the panel label. it will say something like 20-40, or perhaps 20-30, etc. How many circuit breakers are in place now? Do not count the main breaker, and count each 240 volt breaker as two.

Is there a physical tell-tale sign of whether or not a panel can handle the mini-breakers or Slim-Lines?

My main service panel is a Westinghouse Cat# B24-40 BFN, BSN. I'm needing to make space as well for a feed to my dock sub-panel and was suggested Slim-Lines or mini's I guess. Is there a website i can possibly look up the panel to find out more? Going to Westinghouse.com isn't doing it.

No. It will be implied with the space/circuit numbers or specifically listed by the panel manufacturer. An electrical supply house should be able to locate a breaker listed for your panel. They have access to the breaker manufacturer catalogs which list panel compatibilities. The big box stores do NOT have this information.
