I have a 0-75 Ammeter that I need to install. This meter is a direct connection meter that does not require a current transformer. I am not sure of the proper connection this way. I have always previously insatlled the ones with the CT. Can someone give me the right connection procedures. I want to make darn sure that i hook it up right. Thanks, Merlin

A direct connected meter is installed in series with the load.

Directly in series with the load. Take one leg of the load and connect it to the meter. Take the other supply leg and connect it to the meter.

Motor - Meter - Line. Example only

Ok. I thought that was the case but didn't want to let the smoke out not being sure.

Also, bear in mind that the supply will need to be de-energised while this meter is installed, trying to do a job like this with the power still connected is just silly.

Funny, just a little while ago I was thinking about those old ammeters we used to have on the dashboards of our cars.
