ILSPB4-750 ILSCO – 1/0-750MCM 4–Port Panelboard Lug

The ILSPB4-750 is dual-rated (AL/CU), meaning it is listed and suitable for use with both aluminum and copper conductors ranging from 1/0 AWG to 750 MCM. No additional hardware or anti-oxidant compound is mandated by the listing, though applying an anti-oxidant paste to aluminum conductors is always a good installation practice in Canada.

The 3/8" bolt size with 1-3/8" hole spacing is a widely used NEMA-standard bus bar pattern found on many panelboards and switchboards from major manufacturers. However, not every panel uses this pattern — some use narrower or wider spacing. We recommend confirming your panel's bus bar bolt pattern before ordering. Send us your panelboard model number and we'll verify compatibility.

The ILSPB4-750 features 4 independent ports, allowing up to 4 separate conductors (each between 1/0 AWG and 750 MCM) to be terminated in a single lug assembly. This makes it ideal for main lug panelboards or distribution sections where multiple large feeders must land on the same bus connection point.
