What to cover 24v transformer terminals with?


What is the best thing to cover 110v to 24v transformer terminals on the 24v end with? electrical tape just doesn't seem right... on another furnance that has a 24v transformer, the installers covered the termainals with some type of putty stuff it seems like to insulate them its tanish in appearance but seems to of hardened somewhat and seems to cover it good... is there anything like this I could use to cover terminals on a transformer I installed so they dont somehow get shorted out accidently? What do you generally use for this type of situation?

Where is this transformer located that there is a chance on the terminals being shorted? But, if you want to insulate them: You can find liquid electrical insulationin a small can at the apron stores. It's sort of thick, comes with it's own brush, just brush it on, let it get really stiff ( I don't think it ever get's hard) and use multiple coats if you want to. AND-it comes in colors--Red or Black. David

You could wire a solid short circuit to the secondary (24 volt) side of a transformer without any harm.
There are technical reasons for this, but its been so long ago, that I've forgotten why!
Maybe our younger members will know why!
Most codes don't require any protection for voltages of less than 70 volts.
Save your money and take a kid to the ice cream shop.
