I have a customer that I am trying to help. I have several pumps that are identical. Each is rated to draw 9.6 amps and they have a very high failure rate. This is expected and accepted for the application. I want to install an ammeter to monitor the current at a glance. I am thinking that a shunt meter similar to this one is economical and functional.
So my questions and concerns are:
- Is there any advantages that would justify the largely increased cost of proposing CT'd metering instead. physical installation is not an issue.
- I was thinking to install 0-15A range. Given that the circuit is likely to overload often is the meter more prone to damage than say a 0-30A meter? I prefer the 15A because the sensitivity is greater?
