Panel directories printed as magnets by CarStickers.com match the height of the breakers and can be installed over the panel's factory installed labels. This schedule is color coded to indicate circuit priority levels while under generator power.
Smaller round magnetic racing numbers from other sites could be $50-$100. Carstickers.com let me create three large 13” magnets with my choice of colors and font for under $14 each. These magnets are 30mil thickness - perfect for outdoor use. I couldn’t be happier with the product.
