4. Attention points
(1). Can't be touched the joint of the shunt and cable of primary circuit. Secondary voltage can't be sampled from non-sampling point.
(2). It won't be exceed 80% of rated current for long time working. A loop cable (or copper platoon) and shunt connection doesn't allow someone to contact resistance from the sampling point.
