I'm not sure if this is the correct forum to ask this but I'm looking for a "kit" to install an ammeter to detect any ground currents in the neutral>ground connection of an existing panelboard. I've contacted the manufacturer of the panel and they do not have any such kits or products. The existing panelboard is a Square D type NF.
The customer requirement states:
"Ground detection for each ac system that has a grounded neutral should have an ammeter and ammeter switch that can withstand the maximum available fault current without damage. The ammeter should indicate the current in the ground connection and should have a scale that accurately, and with clear definition, indicates current in the 0-A to 10-A range. The ammeter switch should be the spring return-to-on type."
