600-LB1 Load Box
 

 

Overview
Have you ever driven an hour to a test site only to discover that the site had little or no load? With the Spinlab Load Box the Bird Dog Plus can test every site, even if there is no load or a very light load.

In-service testing is the only way to thoroughly test a meter circuit site. If there is no load or a very light load, a proper ratio/burden test cannot be performed. Now with the Load Box, you can load a CT enough to completely test the meter circuit. simply take the current cable from the Load Box, wrap it around the CT, switch from 10 amps to 50 amps through the CT, and perform a meter circuit test the same way as usual. The Spinlab Load Box is usable with 120V, 240V, or 480V service and is good on donut or bar-type CTs.

     

   Some additional applications for Load Box are:

  • Checking CTs on the bench before hooking them up in a circuit.
  • Testing a new installation before a load is applied , saving a later trip back
    to the site.
  • Performing a meter verification test using the Bird Dog Plus on
    no load sites.
