It's been a good while since I wired an entire residential 120v circuit. As best as I can remember, the max load on a 15-amp breaker was about 10 items, plugs and lights combined. Is that about right? Can I run a dedicated 20-amp for a freezer in the garage without a GFCI? How many items can I put on a 20-amp circuit? I live in the Fort Worth, Texas area.
