I've begun thinking about Christmas outdoor decorating. Can anyone help me find a solution for continually tripping a fuse when the lights are plugged in?

It's sad and embarrassing to have our house go dark randomly. Allot of work and time go into decorating and this problem is frustrating and disappointing. Our neighborhood gets tons of traffic as people are coming to see the unique Christmas displays of the homes on our street.

All ideas are needed, helpful and appreciated.
