Electricity requirements

[Howard Lee]

I am setting up my Halloween display and looking for advice on my electrical requirements. I currently have 2 breakers with each breaker have 2 dual outlets with each outlet having a extention cord with a triple tap on the end giving me the ability to plug in 24 items. I need to be able to plug in nearly double that so I'm wondering if I need to install 2 more breakers or can I just pigtail 4 more dual outlets off the outlets I already have?

Okay, first of all, how many amps are you running total?
