Frequently Asked Questions
Conversions Tech inc Insulated Taps & Lugs

Designed and tested for NEC 230.46 compliance, UL 486A/B certification, and AL9CU ratings, Conversions Tech inc insulated taps and lugs set the benchmark for secure, low-resistance connections in every application—from utility service entrances to mission-critical control panels.

1. What distinguishes a Conversions Tech inc insulated tap from a standard mechanical connector?

A factory-molded UV-stable plastisol jacket, pre-filled oxide-inhibitor gel, and removable debris plugs eliminate field taping, cut installation time by up to 40 %, prevent galvanic corrosion, and keep contact resistance below one milliohm for the life of the connection.

2. Are Conversions Tech inc taps and lugs compliant with NEC 230.46 for line-side service conductors?

Yes. Each body is laser-marked “SUITABLE FOR USE ON THE LINE SIDE OF SERVICE EQUIPMENT — NEC 230.46.” Third-party testing confirms compliance, giving inspectors immediate acceptance for meter combos, switchboards, rooftop PV disconnects, and EVSE gear.

3. Which UL standards govern Conversions Tech inc insulated taps & lugs?

All models are cULus-listed to UL 486A/B (Wire Connectors) for 600 V AL9CU applications, and specific direct-burial variants also meet UL 467 for grounding and bonding.

4. What conductor size range and ampacity do the standard four-port taps support?

#14 AWG – 3/0 AWG with dual ratings: 100 A (aluminum) and 130 A (copper) at 90 °C. Custom barrels reach 250 kcmil and 255 A copper.

5. What torque values should be applied to the set screws?

Typical torque: 35 in-lb (#14–#10 AWG); 45 in-lb (#8–#4 AWG); 50 in-lb (#2–1/0 AWG); up to 275 in-lb for 250 kcmil. Always follow the torque etched on each connector.

6. How does the oxide-inhibitor gel extend service life?

The conductive grease displaces air, blocks moisture, and mitigates galvanic action between dissimilar metals, ensuring stable micro-ohm resistance even after thousands of thermal cycles.

7. Can these connectors be installed outdoors or in direct sunlight?

Yes. The plastisol jacket is UV-resistant, chemical-inert, and abrasion-tough, making it ideal for rooftop PV arrays, HVAC disconnects, pole-top reclosers, and coastal switchgear.

8. Are direct-burial versions available?

Yes. DB-series taps carry UL 467 endorsement for direct burial in earth or concrete without additional potting compounds.

9. What operating temperature range do the connectors support?

−45 °C to +90 °C continuous. Elastomer flexibility is retained at −45 °C; insulation integrity remains intact at 150 °C for five seconds during short-circuit events.

10. Why choose a single-side entry design in crowded enclosures?

Landing all conductors from one face minimizes bend-radius space, freeing real estate inside meter sockets, switchboards, data-center PDUs, and switchgear gutters.

11. May the plastisol jacket be painted for phase identification?

While the jacket accepts most epoxy and urethane paints, Conversions Tech inc offers factory-colorized jackets (black, red, blue, white, green) for permanent phase or polarity coding without field painting.

12. Do the taps support IEEE 837 grounding conductor requirements?

Yes. Grounding-specific models include a serrated oxide-inhibitor compound and achieve pull-out forces exceeding IEEE 837 Annex C for substation grounding conductors.

13. Are tamper-proof or shear-head set screws available for utility metering?

Yes. The UT-series features tri-wing shear heads that break off at the correct torque, leaving a tamper-resistant stump accepted by major North American utilities.

14. Can these connectors be used on 1 kV DC solar combiner circuits?

Yes. The dielectric withstand is 1,000 V AC / 1,500 V DC for 60 seconds with no flashover, meeting UL 1741 DC insulation requirements.

15. What is the shelf life of pre-filled oxide-inhibitor taps?

Ten years in unopened packaging at −10 °C – 40 °C. The inhibitor’s base oil remains stable; however, Conversions Tech inc recommends a visual check after five years in high-temperature storage.

16. Can a tap be re-used if a conductor is removed?

UL 486A/B classifies these as single-use; replacing conductors voids the listing. Always install a new tap to maintain UL compliance.

17. Is dielectric breakdown a concern at 1000 V insulation tests?

No. The plastisol compound withstands 2.5 kV AC for one minute with ≤ 0.5 mA leakage—double the standard 1 kV field-megger requirement.

18. Are Conversions Tech inc insulated taps suitable for Class I, Division 2 hazardous locations?

Yes, when enclosed in a suitably rated explosion-proof or purged enclosure. The connectors themselves do not spark under IEC 60079-14 load-pull tests.

19. What short-circuit current rating (SCCR) do these lugs support?

When installed per UL 508A supplement SB in a copper bus bar, testing confirmed 200 kA RMS symmetrical withstand at 600 V AC for three cycles.

20. How is strip-length controlled to ensure proper insertion depth?

Each port rim is laser-etched with a gauge line; stripping to this mark guarantees full screw engagement without conductor protrusion.

21. Are torque-limiting drivers required?

Field installers should use calibrated torque screwdrivers or 1/4-inch torque keys. For production lines, Conversions Tech inc supplies color-coded, torque-pre-set bits.

22. Do the connectors meet CSA C22.2 for Canadian installations?

Yes. The cULus mark denotes compliance with CSA C22.2 No. 65 for wire connectors, authorizing use across all Canadian provinces.

23. Are transparent jackets available for visual conductor inspection?

Yes. The IT-CLEAR series uses a crystal-clear PVC-free jacket allowing visual confirmation of strand seating and inhibitor coverage.

24. How many make/break cycles were tested for reliability?

A 500-cycle make/break endurance per UL 486A/B with zero thread galling and < 2 % contact-resistance drift.

25. What vibration testing has been completed for transportation sectors?

Connectors passed IEC 60068-2-6 sinusoidal vibration (5 Hz – 500 Hz, 6 g) and MIL-STD-810H random vibration profiles for railcars, marine, and heavy truck applications.

26. How are counterfeit connectors identified in the field?

Genuine Conversions Tech inc taps include a holographic date-code label and serialized QR code traceable to lot-level torque and alloy certifications.

27. Is there a maximum installation altitude?

Tested to 5,000 m (16,400 ft) per IEC 60664-1; derating is unnecessary because the jacket’s dielectric strength exceeds altitude-related partial-discharge thresholds.

28. Can these taps be used with bi-metal conductors such as ACSS or ACCC?

Yes, provided strand diameters fall within the AWG range. The inhibitor prevents corrosion between aluminum core strands and outer high-strength steel or composite strands.

29. How do plastisol and EPDM jackets compare?

Plastisol offers superior UV and chemical resistance with a smooth finish; EPDM provides higher flexibility at extreme cold. Conversions Tech inc selects plastisol for optimal long-term dielectric stability.

30. Are railway-specific versions certified to EN 50155?

Yes. RAIL-grade taps meet EN 50155 temperature, vibration, and shock standards for rolling-stock equipment, along with NF F 16-101 fire-smoke classification.

31. How is excess oxide inhibitor cleaned after conductor seating?

Simply wipe with a lint-free cloth; the semi-synthetic base oil is non-conductive and will not attract dust if a thin residue remains.

32. Do Conversions Tech inc taps maintain integrity after 3,000-hour salt-fog exposure?

Yes. Independent ASTM B117 testing showed < 5 % surface corrosion and < 1 % resistance change after 3,000 hours—surpassing typical marine-grade benchmarks.
