Mechanical splice for 750-250 kcmil conductors

The Burndy AMS750 is a mechanical connector designed to splice aluminum or copper conductors ranging from 250 kcmil to 750 kcmil. It provides four termination points for two conductors and features a tin-plated aluminum body with a hex socket head style. The connector is rated for a maximum voltage of 600 V.

Sustained load performance at 600 V

Under continuous electrical load, the connector maintains a secure joint through its mechanical compression design. The tin-plated aluminum body resists oxidation at the contact surfaces to preserve conductivity over time. It is rated for a maximum operating temperature of 194 degrees F, which defines its thermal limit during sustained current flow.

Thermal and power characteristics

Normal operation sees the connector body temperature rise with current flow up to the 194 degrees F limit. The aluminum construction dissipates heat from the joint area without active cooling. There are no moving parts or fans, so the device operates silently. Power draw is determined entirely by the circuit load up to the 600 V rating.

Questions about this item

How much heat can the AMS750 splice handle when it carries load all day?

The connector is rated for a maximum operating temperature of 194 Degrees F, so it stays within spec during continuous use.

What wire sizes and tools must I already have to install this splice?

It accepts stranded copper from 250 kcmil up to 750 kcmil and uses a 15/16 in hex socket head for tightening.

Will this splice work with the older aluminum bus bar I plan to keep in the panel?

Yes — the tin-plated aluminum body is listed for both aluminum and copper conductors, so it connects to your existing bar without dissimilar-metal issues.
