Vertiv ITA2-08KMBCSL2 8kVA L21-30 Dual Input Cordset Kit
Overview
The Vertiv ITA2-08KMBCSL2 is a three-piece cordset kit engineered to convert the hard-wired connections on Liebert ITA2 8kVA UPS systems and rack-mount Maintenance Bypass Cabinets (MBC) to cord-and-plug terminations. That single change transforms what would otherwise be a licensed electrician shutdown into a field-serviceable swap — a real operational advantage in live data center environments where downtime carries a cost. If you are commissioning an ITA2-08KMBCSL2 for a dual-input MBC installation, this kit covers both input feeds and the output connection in one part number.
Key Features
- Three-cord kit in one SKU: The package includes two main input cords (10 ft / 3.05 m each) with L21-30P plugs and one main output cord (1 ft / 305 mm) with an L21-30R receptacle. Having all three cords in a single order eliminates the sourcing gap that leaves a UPS stranded mid-installation.
- L21-30 locking connectors: NEMA L21-30 twist-lock plugs and receptacles resist accidental disconnection under vibration — critical in raised-floor environments where cable disturbance is an everyday hazard. The three-phase configuration handles the 8kVA load without derating.
- 10 ft (3.05 m) input run: The 10-foot input cords give enough slack to reach a typical PDU or distribution panel without strain relief compromises, while keeping cable management clean in a standard cabinet row.
- Dual-input system support: This kit is rated for use with the 8kVA rack-mount MBC in a dual-input configuration — meaning both utility feeds are terminated with matching L21-30P plugs, enabling true source redundancy without custom wiring at the cabinet.
- Stand-alone UPS compatibility: When no external MBC is in the circuit, the ITA2-08KMBCSL2 works equally well as the sole cord set for a stand-alone 8kVA ITA2 UPS — one kit, two deployment scenarios.
- Hard-wire to cord conversion: Converting from a hard-wired termination to a plug-and-cord arrangement means future UPS replacements or MBC swaps do not require an electrician on-site for the disconnect. That translates directly to faster mean-time-to-restore in a hot-swap scenario.
Integration & Compatibility
The ITA2-08KMBCSL2 (also searched as ITA2 08KMBCSL2) is compatible with the Liebert ITA2 8kVA UPS system and the Liebert 8kVA-rated rack-mount MBC for dual-input deployments. Verify your UPS frame accepts cord-and-plug termination before ordering — this kit replaces a hard-wired connection and is not interchangeable with cordsets designed for other kVA ratings in the Vertiv Liebert UPS line. For facilities integrators specifying enterprise UPS solutions, confirm the panel circuit is wired to NEMA L21-30 before finalizing the installation plan. Pair with appropriate power distribution infrastructure rated for three-phase 30A service.

Frequently Asked Questions
Q: What UPS systems is the ITA2-08KMBCSL2 compatible with?
A: The ITA2-08KMBCSL2 is compatible with the Liebert ITA2 8kVA stand-alone UPS and the Liebert 8kVA-rated rack-mount Maintenance Bypass Cabinet (MBC) in a dual-input configuration.
Q: How many cords are included in the ITA2-08KMBCSL2 kit?
A: The kit includes three cords: two main input cords (10 ft / 3.05 m each) with L21-30P plugs, and one main output cord (1 ft / 305 mm) with an L21-30R receptacle.
Q: What connector type does the ITA2-08KMBCSL2 use?
A: The input cords terminate in NEMA L21-30P twist-lock plugs; the output cord uses a NEMA L21-30R receptacle. These are three-phase 30A locking connectors.
Q: Can the ITA2-08KMBCSL2 be used without an external MBC?
A: Yes. The kit supports both stand-alone 8kVA ITA2 UPS deployments (no external MBC) and dual-input rack-mount MBC configurations.
Q: What is the cord length on the input cords?
A: Each input cord is 10 ft (3.05 m) long, providing adequate reach in standard cabinet-row layouts without requiring extension cords.
The ITA2-08KMBCSL2 is one of those parts that looks like a line item until you need it at 2 a.m. during a UPS swap. The kit's dual 10 ft (3.05 m) L21-30P input cords are sized for real cabinet rows — long enough to reach distribution without slack management problems, short enough to keep the run tidy. Getting all three cords (two inputs, one output) in a single part number is the right call for a planned maintenance window.
Technical Highlights:
- Dual 10 ft input cords: At 3.05 m each, these give you enough reach to a wall-mount PDU or overhead busway without stacking extension cords — a shortcuts that creates ground fault risk in three-phase circuits.
- L21-30 twist-lock terminations: The locking connector format matters under raised-floor conditions where cable foot-traffic is constant. Straight-blade alternatives would need mechanical retainers; L21-30 handles it natively.
- Single-kit dual-input coverage: The kit is explicitly rated for the 8kVA MBC dual-input configuration — both upstream feeds are matched L21-30P, which keeps your panel labeling and circuit documentation consistent across both input legs.
Deployment Considerations:
- Confirm your panel receptacles are wired for NEMA L21-30 three-phase 30A service before this kit ships — retrofitting the panel circuit adds lead time that kills the maintenance window schedule.
- The 1 ft (305 mm) output cord is intentionally short; it connects the UPS output directly to the MBC input in close proximity. Do not substitute a longer cord here — impedance and voltage drop matter at 8kVA load levels.
This kit is the right call for data center facilities teams commissioning ITA2 8kVA UPS systems in dual-input MBC rack configurations where future serviceability without a licensed electrician on standby is a design requirement.
