There are a few different ways.

If there is a disconnect before the panel, it is usually labeled with it's max capacity or what the maximum fuses are, assuming it is a fused disconnect.

If no disconnect is present, look at the main breaker for the entire panel. You can always check the main wires coming into your panel but opening a panel is EXTREMELY DANGEROUS and should only be attempted by a trained Electrician.
