Never mind. This one need to be installed in the circuit. Not sure of the
advantage other than isolation.

All we've ever bought are the 10A version. They read accurate enough to
see when a 1/2 or 1A DC-UPS is charging as well as 3-7A the other
direction when the load is running on battery. Typical 24 and 48VDC

Because Forrest makes them in a nice little DIN rail package and
designed to work on his SiteMonitor base
.1 volt/20 amps is .005 ohms.
So, 2 feet of 14 gauge will produce 100 mV at 20 amps.
Just feed it into the SiteMonitor.

Of course this assumes you have the room for and don't mind the look

There will likely be a 20A shunt in our future.I'm in the process of
redesigning these so that they're less expensive to build since the
existing design is being sold at or possibly below cost. I'm trying to end
up with a 20A shunt as a result but I don't know for sure if this will
happen.

This may be a bozo approach, but if you took two 10 amp shunts and
connected them in parallel, you would get a 20 amp shunt out of the deal.

Reason I'm asking is... I'm stupid. I had a 10A shunt on the batt
negative side of a Traco BCMU360. Didn't occur to me that 230 watts @
~12VDC can get up to 20A. So the shunt went kaput afte
