Supplying Demand BRK3 Fuse Pro 3 AMP Tester with Light Plugs Into PC Board

I do heating and a/c work daily. I had purchased the 5 amp version of this and liked it but felt the 5 amp version did not trip fast enough. So I purchased the 3 amp version and they both plug right into control boards with a standard automotive fuse. They work great for trouble shooting low voltage wiring problems.

I’ve used this product several times locating low voltage shorts in HVAC systems. Works great!

Great on every call saves me a ton of fuses.
