3Lo/ 2Lo tests are used when we have RCD/ RCBO on the circuits. As the Ze and PFC were carried out at the origin of supply with no risk to trip breakers, I used the 2Hi test.
@@freezefoot If the second DB was not connected to the origin and was fed off the first DB on RCD/ RCBO protection then yes I would carry out "Low" test however if the second DB was supplied directly from the meter (Henley blocks) then I would still carry out the 2/3 lead High test.
New subscriber.Thank you for this video.What makes you decide on 2Hi as opposed 3Lo.Which one is more accurate and why?Thanks again

@@MHKBuildingSolutions So you would use 2 Hi for Ze but if you had a ZDB downstream you would use 3lo/2lo.Have I understood this correctly?Thank you .

@@MHKBuildingSolutions Understood.Thank you
