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

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

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.

Great on every call saves me a ton of fuses.
