[Spridgets] No LBC - Any electricians out there?

[bmwwxman at gmail.com (Jim Johnson)]

If you can help, please contact off list.  Am replacing ancient service
panel and breakers. How do I tell what the old breakers are rated in Amps?
Only marking I find on them is  M0-8 and M0-1.  I'm guessing 15 Amps in
this old house...

TIA,
Jim
