Torque Spec

[Wastedwagesracing]

Where can/do I find the proper torque spec for 4/0 Aluminum wire?

If you are installing it in a panel or other piece of equipment, the instruction placard in the panel door, or information accompanying the device should have the torque spec.

Well that is just my luck. It's a used but in very good condition 400 amp disconnect. Of course I thought well I should clean it up a bit. Yup the cleaner took the writing off of the sticker on the door.

Look up the disconnect on the manufacturer's website and see if the catalog pages show the torque spec.

If you can't find the exact specs, 250-275 inch pounds is close to what is needed or 20-22 foot lbs. for 4/0.

Watch this Youtube video about torquing wire.

You may want to use a pin connector ,just crimp it on the aluminum and install it in the lug .
it will solve any loose connection issues.

You'd still have to torque the lug, wouldn't you?
