Projecta BT620-N1 Negative Saddle With Dual Auxiliary Brass Battery Terminal, Blister of 1

Quick answer

The Projecta BT620-N1 is the Negative Saddle With Dual Auxiliary Brass Battery Terminal, Blister of 1. Need to replace just one clamp? The BT620-N1 is a single negative saddle with dual auxiliary terminal.

Need to replace just one clamp? The BT620-N1 is a single negative saddle with dual auxiliary terminal. Size the cable first: this one is listed for 50 to 70 mm², 0 to 00 B and S.

The dual auxiliary outlets suit 5 to 15 mm², 10 to 6 B and S wire, so accessory leads land on the terminal instead of being piled on the post bolt. The main cable clamps under the saddle while the auxiliary outlets handle lighter accessory wiring. Forged brass conducts well and copes with the heat and vibration of an engine bay.

Positive posts are slightly larger than negative posts, so fit this one only to the negative side. Before fitting, clean any corrosion off the post so the terminal seats properly.

Keep the positive covered so a spanner cannot bridge it to the body. If the old terminal was badly corroded, cut the cable back to clean copper before fitting the new one. See the rest of the <a href="https://frankiesautoelectrics.com.au/collections/projecta">Projecta range</a> for matching parts.

FAQ

Which cable sizes fit the saddle with dual auxiliary BT620-N1?

Projecta lists 50 to 70 mm², 0 to 00 B and S for the main cable.

What size accessory wire goes in the dual auxiliary outlets on the BT620-N1?

The auxiliary outlets take 5 to 15 mm², 10 to 6 B and S cable, so lighter accessory feeds connect at the terminal. Fuse each feed to suit the cable.

Will a negative saddle with dual auxiliary terminal fit the opposite post?

No. Positive posts are slightly larger than negative ones, so this negative terminal is sized for the negative post only.

My old saddle with dual auxiliary terminal is cracked; can I just swap in the BT620-N1?

Cut the cable back to clean, bright copper if the old end is green or black, then fit the new terminal and tighten it firmly.

How do I stop the saddle with dual auxiliary BT620-N1 going green on the post?

Once it is tight, a thin coat of terminal grease or protector spray over the joint slows corrosion.
