Current Clamp Assembly parts diagram: 1 split-core toroid, 2 secondary winding, 3 burden resistor, 4 clamp housing, 5 shielded CT cable. 8 parts in 5 top-level items. — Current Clamp Assembly parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	Part	Qty	What it does
1	Split-Core Toroid	2×	Split ferrite or silicon-steel toroid, clipping around service line without disconnection
2	Secondary Winding	2×	Secondary winding (hundreds of turns) stepped down from 100–200 A primary to 5 mA at full scale
3	Burden Resistor	1×	1 kΩ precision burden resistor converting 5 mA secondary to 5 V signal
4	Clamp Housing	1×	Molded plastic clamping mechanism with spring-loaded jaws, rated IP54 for utility enclosure (weather exposure)
5	Shielded CT Cable	2×	Shielded two-conductor cable from each CT clamp to measurement unit, 25–50 feet length typical
