Burndy KPU34A26AC – Frequently Asked Questions

1) What conductor sizes does the Burndy KPU34A26AC gutter tap connector accept on the run and the tap?
The KPU34A26AC POLYTAP takes a 4/0 AWG stranded through 500 kcmil run conductor and a tap from 14 AWG solid up to 2/0 AWG stranded. Same run range on aluminum, 4/0 AWG to 500 kcmil. On the aluminum side the tap range is narrower, 8 AWG through 2/0 AWG, so if you are tapping smaller than 8 AWG that tap has to be copper.
2) Can I tap aluminum feeders to copper branch conductors with this connector?
Yes. The POLYTAP KPU34A26AC is a copper-aluminum (AC) rated connector and suits all copper/aluminum combinations, so aluminum run to copper tap, copper run to aluminum tap, or all one metal are all acceptable. The body is tin plated, which is what makes the dissimilar-metal connection acceptable.
3) What torque should I use when installing a Burndy POLYTAP KPU34A26AC?
450 in-lb is the recommended installation torque. Use a torque wrench on it rather than feel, since an under-torqued aluminum connection is where heating starts, and re-check the tap after the conductors have seated.
4) Is the Burndy KPU34A26AC UL Listed for service entrance and gutter tap use?
UL Listed, and built to UL468A-468B, the standards covering mechanical wire connectors. Typical use is electrical gutter and panel wiring, service entrance wiring, and commercial or industrial copper-to-aluminum taps. Note it is not CSA approved and does not carry a cULus or UL direct burial listing, so for Canadian work or a buried application you need a different connector.
5) Is this an insulated tap, or do I have to tape and cover it after install?
It comes with a full insulated cover over the tap connection, so no field taping or separate insulating boot is needed. That is the difference between the POLYTAP and a bare mechanical tap block, and it is why it gets used in gutters and panels where conductors are crowded together.
6) How is a gutter tap connector different from a split bolt or a terminal lug for tapping a feeder?
A gutter tap like the KPU34A26AC is a single insulated body that takes the large run conductor straight through, undisturbed, and clamps a smaller tap off it, so you never cut the feeder. A split bolt gives you the same electrical tap but leaves a bare connection you have to tape up, and a terminal lug terminates a conductor onto a bus or pad rather than tapping mid-run. For a 4/0 to 500 kcmil feeder running through a wireway with a 14 AWG to 2/0 branch coming off it, the insulated gutter tap is the one that saves you the field insulating work.
7) What is the exact Burndy part number and how many come in a pack?
Order it as Burndy KPU34A26AC, POLYTAP series, sold with a minimum pack quantity of 1 so you can buy single pieces rather than a carton. Burndy also references the product family as KPU-AC.
8) Will the tin plating hold up in a damp mechanical room or outdoor gutter?
The body is tin plated for corrosion resistance, which is what you want on a copper-to-aluminum joint in a humid or industrial environment. It is not rated for direct burial, though, so keep it inside an enclosure or wireway.
