Thomas & Betts GP-2 Aluminum Parallel Tap Connector, 4-14 AWG, Dual-Rated

The GP-2 takes taps from 4 to 14 AWG, and the main run per the product designation is 2 through 12 AWG stranded. So it handles the common branch-tap combinations you see in gutters, pull boxes, and panel feeds within that range. Outside 4-14 AWG on the tap leg, you need a different body size.

Yes. The GP-2 body is aluminum with a tin plating, which is what makes it dual-rated for copper or aluminum conductors. The tin plate is the barrier that keeps aluminum from contacting copper directly, so copper-to-aluminum, copper-to-copper, and aluminum-to-aluminum taps are all acceptable in the same connector.

No. The GP-2 is built for a 2-12 AWG stranded main with a 4-14 AWG tap. For heavier runs, look at a larger-capacity clamp such as the Burndy UC25R2RS Tapit parallel groove clamp in aluminum alloy, or a two-bolt copper connector like the Burndy KVS34 run and tap splice.

The nearest equivalent is the Burndy UC25R2RS Tapit parallel groove clamp, which is also an aluminum alloy parallel groove tap clamp. Like the GP-2, it makes a parallel tap between a run and a tap conductor with a mechanical clamp rather than a crimp. The GP-2 itself is an aluminum tap connector with a tin-plated finish and a tap range of 4 to 14 AWG, so if you need those specific conductor sizes covered, confirm the Tapit clamp's range against your run and tap before swapping.

Use the Burndy KPU34A26AC POLYTAP insulated copper-aluminum gutter tap connector. It is supplied insulated and is intended for gutter and wireway taps, so no separate taping or boot work is needed at the connection. The Thomas & Betts GP-2 is a bare aluminum tap connector with a tin-plated finish, so it relies on field-applied insulation where the installation requires it.

Look at the Burndy KVS34 two-bolt copper connector for run and tap splices. It is a copper-bodied two-bolt clamp built for run-and-tap splicing, which suits all-copper work on heavier conductors. The Thomas & Betts GP-2 is an aluminum-bodied, tin-plated parallel tap connector with a tap range of 4 to 14 AWG, so it is aimed at smaller taps; the tin plating is what allows it to be used on copper as well as aluminum.

A mechanical parallel tap like the GP-2 clamps the run and tap with a set screw, so it installs with a hex driver or wrench and can be opened again if the tap has to be moved or re-terminated. A compression connector such as the Burndy CRIMPIT C-tap is crimped with a die tool and is permanent once installed. Pick the mechanical tap when you want serviceability and no crimp tool on the truck; pick the compression type when you want a sealed, non-reusable joint.

The GP-2 is a bare tin-plated aluminum connector, so insulating it is on the installer unless the enclosure provides the required separation. If you want the insulation built in, the Burndy POLYTAP KPU34A26AC is an insulated copper-aluminum gutter tap connector.

Not a direct one. The Burndy CRIMPIT C-tap is a copper compression run/tap connector, meaning it is installed with a crimping tool and is not reusable or adjustable once compressed. The GP-2 is a mechanical aluminum parallel tap connector rated for 4 to 14 AWG taps, installed with a wrench or screwdriver and removable. If you do not have a compression tool on the truck, or you need to break the tap later, the mechanical GP-2 is the one to specify.

The Thomas & Betts GP-2 and the Burndy UC25R2RS Tapit parallel groove clamp are both mechanical clamps that tighten onto the conductors with hand tools. By contrast, the Burndy CRIMPIT C-tap is a compression connector that requires a crimping tool to install. For an electrician doing occasional taps in a panel or junction box, the mechanical route avoids carrying a crimper and dies.

Yes. The Thomas & Betts GP-2 aluminum parallel tap connector is listed under UL file E9809, which matters on inspected commercial and institutional work where the tap device has to be a listed connector. It is a dual-rated device for copper and aluminum conductors with a tap range of 4 to 14 AWG, so one part number covers both conductor metals in that size band instead of stocking a separate copper-only clamp such as the Burndy KVS34.

The GP-2 sells each, so one connector per unit ordered. For a multi-circuit gutter tap where you need a connector per phase plus neutral, order the quantity to match.

Order Thomas & Betts GP-2. That is the manufacturer part number for the tin-plated aluminum parallel tap connector rated for a 2-12 AWG stranded main and a 4-14 AWG tap.
