About this fuse

The Allied Innovations 20 Amp AGC Fuse is a premium glass electrical protection component designed for spa and hot tub systems. This standard AGC-type glass fuse provides reliable 20-amp circuit protection for various electrical components in your spa's control system, including pumps, heaters, and control boards that require this specific amperage rating.

Built to OEM specifications, this genuine Allied Innovations fuse ensures exact fit compatibility with your spa's electrical panel. At Bubbles Supply, we guarantee the perfect fit with same-day shipping on in-stock items and back every fuse with our comprehensive 1-year warranty. Always verify the amperage rating marked on your existing fuse before replacement, and ensure power is completely disconnected before installation. Replace blown fuses only with the exact same amperage rating to maintain proper electrical protection for your spa system.

Before you buy — quick checklist

Pull the existing fuse and confirm it is stamped or printed AGC-20 — do not replace with a different amperage
Verify the fuse holder accepts a standard AGC (1/4 inch x 1-1/4 inch) form factor
Inspect the fuse holder clips for corrosion or burn marks — a damaged holder can blow replacement fuses immediately
Identify why the original fuse blew before installing a new one — a fuse blown by an underlying fault will blow again
Confirm this is an AGC fast-blow type; do not substitute a slow-blow (MDL or MDX) fuse of the same amperage

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
