Burndy PENA4 – Frequently Asked Questions

1) Can Burndy PENA-4 joint compound be used on aluminum-to-copper connections, or is it aluminum only?
The PENA-4 antioxidant compound is formulated for aluminum-to-aluminum, aluminum-to-copper, and aluminum-to-conduit joints. So a dissimilar-metal termination, aluminum conductor into a copper or tin-plated copper lug, is a rated use for it, not an off-label one. That covers most of the mixed-metal work an electrician runs into on service and panel terminations.
2) Is the PENA-4 antioxidant compound UL Listed for electrical joints?
Yes, the PENA-4 compound is UL Listed. Note it is UL Listed rather than UL Recognized, and it does not carry a CSA certification or a cUL/cULus mark. If your inspector or spec requires a Canadian mark on the compound, this one will not satisfy it. It is also RoHS compliant.
3) Do I need antioxidant compound when terminating aluminum conductors in a lug?
Aluminum forms an insulating oxide layer on its surface almost immediately, which drives up resistance at the contact point and can lead to a hot connection. A compound like the PENA-4 is brushed onto the conductor and lug contact surfaces to break through and seal out that oxide. It is rated for aluminum-to-aluminum, aluminum-to-copper, and aluminum-to-conduit joints, which covers lug and wire connector terminations on aluminum feeders. Many aluminum-bodied connectors ship pre-filled; this bottle is for the ones that do not, and for re-terminations.
4) Will antioxidant joint compound run out of an aluminum lug when the connection heats up?
The PENA-4 compound has a dropping point of 230 degrees F, which is the temperature at which it starts to flow out of the joint. Normal conductor operating temperatures sit well below that, so it stays in place on a properly torqued termination. Viscosity is 305 at 100 degrees F, thick enough to stay where you brush it on a vertical bus or lug face.
5) Can I use this Burndy joint compound on a cold-weather outdoor install?
Pour point on the PENA-4 is -15 degrees F, so the compound is still workable and will still dispense in freezing conditions, which matters when you are terminating aluminum service entrance conductors outside in winter. Below that point it stops pouring and you will want it warmed up before application.
6) What is the exact part number to order this Burndy antioxidant compound?
Order it as Burndy PENA-4 (manufacturer part number PENA4). That designation is the 4 oz. squeeze bottle of antioxidant joint compound; Burndy uses other suffixes for different container sizes and styles, so the -4 is what identifies this package.
7) How much compound is in a bottle of PENA-4 and is the container practical for field work?
It is 4 oz. in a squeeze bottle, so you apply it directly to the conductor or lug pad without a brush or dipping out of a can. That size suits a service truck or a handful of terminations rather than stocking a large bus job, where a larger container makes more sense.
