ReplyIt should read low voltage between r and common, why would anything trip?
If you're talking about trouble shooting low voltage shorts, I use a 3 amp circuit breaker instead of going through boxes of fuses.
I don't see the point of your "tool".

Hey guys
Let me know what u think of this tool ive come up with.
Its a safty jumper! It would have one clip one each side of wire, in the middle of the wire it would have a silver dollar size conponit wich has a digital screen to measure voltages, the kick is if u were to jump the wrong wires say like r and common it would trip setting off a red led light saving the fuse or transformer ect, then u would push the reset button and try it again,
I think this would be usefull for new guys as well as a vet. After the first trip it would pay for itself as well as save u time and money. What do u guys think let me know

I think the idea is to just have a simple troubleshooting tool for low voltage apps. Normally when I run into a low voltage situation, I just wire in my 75 VA step down transformer with a built in circuit breaker. That way, even if the original transformer is toasted, I've got an immediate emergency power supply and will put in a spade fuse after I fix the short. If the unit originally had a fuse protecting the circuit, then I just replace the fuse when done. Good thought process for the OP but I think we've got that one covered.
If YOU want change, YOU have to first change.
If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!

Sounds like a " lil Popper" with a voltage readout.

Sounds like someone needs to learn to use a meter.

That's the first thing I thought of also.....

Some systems are not protected by a fuse, i like the transformer idea. This is a tool more for entry level guys, i guess the point would be to prevent techs from shorting out conpoinents.

A properly applied and utilized multimeter won't short out a system or blow a fuse, either.

Ditto ..... i know a few in real life who get sent on service calls who have no idea how to read voltage. Pretty scary i.m.o

Furlo, if we teach the entry level guys the right way to troubleshoot a circuit then they can excel much better .. Well i.m.o anyway. Hell the guy i mentioned in my previous post can jump out a stat btw lol. But he can't troubleshoot it

I would say there are alot of hvac guys who need to learn how to read a meter.

So let's not do anything to make that easier for them to ignore.

You can already purchase a reset low voltage short device at almost any electronics store. Just add some clips.
Some of the Yorks and Carriers have them built into the system.
Every time it trips reset and move on until you locate the short.

How are you going to read a voltage with this tool unless the "reset component" is tripped?
If you can't fix it with a hammer, you've got an electrical problem.
