Note

●  When the test voltage injection clamp is connected close to the  

distribution board, KEW 4506 can test the outlet which is wired 

to branch circuit breaker [B] shown in Fig. 6-15 and judge as 

“PASS” (correct); however, it is NOT recommended to connect 

test voltage injection clamp to the position shown in Fig. 6-16. 

    This  is  because  KEW  4506  may  show  “

” if multiple 

loads  are  connected  to  an  outlet  wired  from  any  of  the  other 

branch circuit breakers, which is not the one to be tested, and 

where those loads are active.

 

Power supply 

Other branch circuit 

breakers [correct]

 

Branch circuit breaker [B]

Branch circuit breaker [A]
