Ammeter Shunt

[Julien]

Hello, I would like to install the ammeter shunt with the EMS D-10.

In the installation guide, it is suggested to fuse the connections between the shunt and the EMS. It is written that it is possible to use a fuse or to use butt splices.

I did not understand the second solution. How will the butt splice protect the EMS in case of short-circuit ? Will it melt with a high-current and open the circuit ?

As it says in the install manual:

"Or, you may use butt splices to connect 1” to 2” sections of 26 AWG wire between the shunt and each of the Amps leads connecting to the EMS-D10. These fusable links are cost effective and simple way to protect against short-circuit failures."

It's not the butt splices that protect you, it's the 26 gauge wire that does. If a short circuit occurs, these wires will melt instantly and act as fuses.
