Panduit SCS4-L – Frequently Asked Questions

1) What wire sizes does the Panduit SCS4-L compression splice accept?
The SCS4-L takes #4 to #3 AWG stranded copper and #2 AWG solid copper. The catalogued conductor size is 4 AWG. It's a butt splice, so both conductors go into opposite ends of the same barrel and get crimped separately. Aluminum conductors are out of scope here, the barrel is copper with a tin plating.
2) Can I use a Pan-Lug SCS4-L splice on medium voltage cable?
Yes. The Pan-Lug SCS4-L is UL Listed and CSA Certified to a maximum of 35 kV, with a 90 C temperature rating under both UL and CSA. That covers 600V branch work through MV terminations up to 35 kV, provided your insulation and splice kit are rated to match.
3) Does the SCS4-L come insulated, or do I have to tape or heat shrink it?
It's a bare, non-insulated barrel. You insulate it yourself after crimping, normally with heat shrink tubing or tape rated for the circuit voltage. The gray color code on the barrel is for identifying the wire range on the job, not insulation.
4) I'm splicing aluminum conductors - is the SCS4-L the right part?
No. The SCS4-L barrel is copper, tin-plated, and is rated for copper conductors only. For aluminum or a mixed aluminum-to-copper splice you need a dual-rated AL9CU connector, such as the NSi ASC-T series aluminum compression splice. Putting aluminum into a copper-only barrel is a code and galvanic corrosion problem.
5) Can I use the Panduit SCS4-L to splice aluminum conductor?
No. The SCS4-L is a copper-base, tin-plated splice rated for copper conductors, sized for 4 AWG copper. For an aluminum-to-aluminum or aluminum-to-copper splice you need a dual-rated AL9CU connector such as the NSi Industries ASC-T series aluminum compression splice, part ASC2T. An aluminum conductor put into a copper-only barrel is a code and reliability problem, not a size question, so verify the conductor metal before ordering.
6) What is the closest equivalent to the Panduit SCS4-L compression splice from another brand?
The nearest cross-brand equivalent is the NSi Industries SC series tinned copper compression splice, part SC-4. Both are tin-plated copper butt splices for copper conductor splicing. The Panduit SCS4-L uses a standard barrel and a tin-plated finish over a copper base, while the NSi SC-4 is a short barrel design in the SC series. Confirm the crimp die you have on hand covers whichever barrel you buy - the SCS4-L calls for Panduit die index P29, Burndy die index 8, or T&B die index 29.
7) When should I use a long barrel splice instead of the Panduit SCS4-L?
The SCS4-L is a standard barrel splice, which takes a single compression per conductor side and keeps the body to 1.75 in. (44.4 mm) overall. Where a specification or utility standard calls for additional crimps and greater conductor engagement per side - common on higher-pull or higher-vibration feeder runs - a long barrel splice such as the NSi Industries C series C30 is the design to specify instead. Long barrel bodies are physically longer, so check your splice enclosure or gutter space before switching.
8) How long is the splice body, and will it fit inside a crowded junction box?
Overall length is 1.75 in. (44.4 mm), a standard barrel rather than a long barrel. That compact body plus whatever insulation you add is what you need to account for in box fill and bend radius. If you want more contact area per conductor, a long barrel splice such as the NSi C series is the alternative style.
9) Does the Panduit SCS4-L meet Buy American / ARRA requirements on a federal job?
The SCS4-L is flagged ARRA compliant and RoHS compliant, with no lead or mercury content and no Prop 65 cancer listing. Country of origin is Mexico, which is the detail a government or institutional procurement officer will need to check against the specific Buy American clause in their contract.
10) What's the difference between a short barrel and a standard barrel copper splice?
Barrel length drives how much contact area and how many crimps you get per conductor. The Pan-Lug SCS4-L is a standard barrel at 1.75 in. overall. A short barrel type like the NSi SC series is a more compact body for tight boxes, and a long barrel like the NSi C series gives more crimp real estate. All three are tinned copper butt splices, so the choice comes down to the space you have and the number of crimps your spec calls for.
11) Does the NSi SC-4 short barrel splice drop into the same die as the Panduit SCS4-L?
Do not assume so. The Panduit SCS4-L publishes its crimp tooling as Panduit die index P29, Burndy die index 8, and T&B die index 29, and those indexes are tied to that specific barrel. The NSi SC-4 is a short barrel splice in the SC series, a different barrel geometry, so its die index must be confirmed against the connector before you crimp. Matching wire size alone does not make two splices tool-interchangeable.
12) For a 35 kV rated copper splice in a switchgear cabinet, is the Panduit SCS4-L or an aluminum dual-rated splice the right call?
For copper conductors, the SCS4-L is the direct fit: tin-plated copper, non-insulated, UL Listed and CSA Certified to 35 kV with a 90 degree C temperature rating at both UL and CSA. The NSi ASC2T is a dual-rated AL9CU aluminum-body splice in the ASC-T series, which is what you reach for when the run includes aluminum conductor. Both are non-insulated compression bodies, so either way the splice needs the appropriate tape or tubing build-up for the medium-voltage application.
13) If I am standardizing a panel shop on one copper splice, what differentiates the Panduit SCS4-L from the NSi C series?
Both are tinned copper compression splices. The Panduit Pan-Lug SCS4-L is a standard barrel body, 1.75 in. long, gray color coded for quick field identification, sold 50 pieces to a package, and is ARRA compliant and RoHS compliant. The NSi C30 is a long barrel tinned copper splice in the C series. Standardizing on the standard barrel keeps one die index set in the crew's tool case; standardizing on long barrel gives you a single part that satisfies specs written for multi-crimp splices.
14) How many Panduit SCS4-L splices come in a pack?
Standard package is 50 pieces, sold by the pack. Minimum order is 1. The 50-count pack weighs 1.55 lb and measures 4.75 x 3.35 x 3.4 in.
15) Why tin-plated instead of bare copper for a splice in a damp or outdoor location?
The tin plating over the copper barrel slows oxidation at the crimp interface, which is where resistance and heat build up in a bare copper splice exposed to moisture or industrial atmosphere. Combined with the 90 C rating, that's why these get specified in switchgear, panelboards, and power distribution rather than a plain mechanical connector.
