When you are working high voltage, 277/480, high legs or stinger legs, WYE or Delta it is very important to let us know the wiring configuration at the location. We make and calibrate the meters specifically for your needs, so if you don’t have a neutral or one leg is higher than the others please let us know up front.
Typically speaking if you are dealing with high voltage you should be a professional. We will only sell high voltage meters to people that know what they are doing. Please call us to place an order for any high voltage meter you might need for any application up to 1600 amps.
