Middle Atlantic 24S7218IGX99IV Plugmold 20A Isolated-Ground Multi-Outlet Strip
Overview
The Middle Atlantic 24S7218IGX99IV is a 6-foot (1.8 m) steel plugmold multi-outlet strip from the V2400 Series, configured with four duplex isolated-ground (IG) receptacles on a 20-amp circuit. Designed for rack and raceway integration in AV, security, and IT infrastructure environments, this strip addresses the specific problem of ground-loop noise and electrical interference that plagues sensitive electronics — cameras, NVRs, switchers, and audio processing gear — when they share a common ground reference with HVAC, lighting, and other building loads.
TAA compliance makes the 24S7218IGX99IV eligible for federal, state, and municipal procurement contracts where Trade Agreements Act sourcing is a hard requirement. If you're spec'ing equipment for a government facility or DOD-adjacent installation, this is the strip to reach for — not a standard commercial-grade unit that will get kicked back at the compliance review.

Key Features
- Isolated-Ground (IG) Configuration: The IG designation means the ground pin on each receptacle is isolated from the metal strip housing and bonded separately back to the panel. In practice, this eliminates the common-path impedance that causes hum, video noise, and intermittent ground faults when sensitive electronics share outlets with motors or switching supplies on the same circuit. If you've ever chased 60 Hz interference in a surveillance recording room or AV rack, IG receptacles are the engineering fix — not a workaround.
- Four Duplex Outlets across 6 Feet: Four duplex positions spread over 1.8 m give you eight total plug positions with adequate physical spacing between each. In a populated equipment rack, this means you're not fighting transformer-block conflicts or daisy-chaining adapters to fit adjacent gear. The 6 ft length also spans standard floor-to-ceiling raceway runs without mid-run splicing.
- TAA Compliant: Verified TAA compliance means this unit qualifies for GSA Schedule purchases, DoD contracts, and any procurement governed by the Trade Agreements Act. This isn't a paperwork technicality — non-compliant power distribution gets flagged and replaced at the integrator's expense on federal projects. Specifying the 24S7218IGX99IV at design time avoids that cost.
- V2400 Series Steel Construction: The V2400 Series uses steel construction rather than plastic extrusion, which matters in two ways: physical durability in high-traffic or maintenance-access environments, and the grounded metal housing provides EMI shielding that plastic strips cannot. For rack-mounted surveillance or access control equipment that operates 24/7, the mechanical and electrical robustness of steel is the correct choice.
- 20-Amp Circuit Rating: Rated for 20A service, this strip is paired to a dedicated 20A branch circuit — standard for AV and security rack feeds. Running a 20A strip on a 15A circuit is a code violation and a thermal risk. Confirm your panel's branch circuit rating before installation; most modern security rack installations are already spec'd at 20A dedicated.
Integration and Compatibility
The 24S7218IGX99IV is designed for surface-mount raceway installation in Middle Atlantic's V2400 Series pathway system, but the strip can also be installed independently in any situation requiring a surface-mounted multi-outlet run. The isolated-ground receptacles accept standard NEMA 5-20P plugs (the 20A T-blade configuration) — confirm that your equipment's power cords are 5-20P or 5-15P compatible (5-15P plugs mate with 5-20R receptacles; the reverse is not true).
For power distribution planning in security and AV racks, pair this strip with a dedicated 20A circuit and appropriate surge protection upstream. IG strips are often used alongside a whole-rack UPS or inline surge suppressor — the isolated ground path must remain continuous through any intermediate device for the IG benefit to reach the end equipment.
This strip fits naturally into infrastructure builds alongside PoE network switches and network video recorders where clean, interference-free power distribution is a system requirement rather than an afterthought. The TAA compliance status also makes it a straightforward pairing with NDAA-compliant cameras and access control equipment in government-facing deployments.

Frequently Asked Questions
Q: What does the IG (isolated ground) configuration mean on the 24S7218IGX99IV, and why does it matter?
A: IG means each receptacle's ground pin is isolated from the metal strip body and runs a separate ground conductor back to the electrical panel. This eliminates ground loops — a common source of 60 Hz hum and video noise in racks where sensitive electronics share a ground path with motors or other noisy loads. It's the correct choice for security, AV, and IT equipment rooms where electrical interference affects equipment performance.
Q: Is the 24S7218IGX99IV TAA compliant for federal and government procurement?
A: Yes. The 24S7218IGX99IV carries verified TAA compliance, making it eligible for GSA Schedule purchases and contracts governed by the Trade Agreements Act. Specify it by MPN on government project submittals to avoid compliance rejections.
Q: How many outlets does the 24S7218IGX99IV provide, and what plug type do they accept?
A: The strip has four duplex positions, providing eight total outlet positions. The receptacles are NEMA 5-20R (20-amp T-slot), which accept both NEMA 5-20P (20A) and NEMA 5-15P (15A) plugs — standard for most rack-mount equipment power cords.
Q: What circuit breaker rating does the 24S7218IGX99IV require?
A: This strip is rated for a 20-amp branch circuit. It must be connected to a 20A dedicated circuit — running it on a 15A circuit violates NEC code and creates a thermal overload risk. Verify your panel's dedicated rack circuit rating before installation.
Q: Can the 24S7218IGX99IV be used outside of Middle Atlantic raceway, or is it specific to the V2400 system?
A: The strip is part of the V2400 Series and is designed for installation within that raceway system, but it can be surface-mounted independently in any application requiring a 20A isolated-ground multi-outlet run. The raceway provides mechanical protection and cable management — useful but not required for the strip's electrical function.
Q: What is the physical length of the 24S7218IGX99IV?
A: The strip measures 6 feet (1.8 meters) in length — sufficient to span standard floor-to-ceiling raceway runs or the full height of a populated equipment rack without mid-run splicing.
The 24S7218IGX99IV is a purpose-built solution for one specific problem: electrical ground noise in sensitive electronics racks. The IG configuration — isolated ground pins running a dedicated conductor back to panel — is the only NEC-compliant way to break ground loops at the receptacle level without introducing additional isolation transformers or conditioners upstream. I specify this strip on government security projects specifically because it clears two gates at once: clean power for the electronics and TAA compliance for the procurement office.
Technical Highlights:
- Isolated-Ground Receptacles (4 Duplex): Eight IG outlets across 6 feet give you the physical spacing to avoid transformer-block conflicts in a populated rack — a detail that matters when you're fitting NVRs, managed switches, and UPS gear side by side.
- 6 ft (1.8 m) Length: Matches standard floor-to-ceiling raceway runs in most commercial installations without requiring a mid-run junction or splice — cleaner install, fewer failure points.
- TAA Compliance: Verified TAA status means this unit clears federal procurement requirements without substitution risk. For GSA or DoD submittals, spec it by MPN and move on — no compliance research required at bid time.
Deployment Considerations:
- Confirm the branch circuit is rated 20A dedicated before installation — the strip is rated 20A and must be fed accordingly. A shared 15A circuit is a code violation and will trip under load from multiple rack devices.
- The IG benefit only reaches end equipment if the ground isolation is maintained through every upstream device. If you're inserting a surge strip or UPS between the panel and this strip, verify that device also passes the isolated ground path — not all do.
This strip is the right call for government security operations centers, broadcast monitoring rooms, and any rack environment where 60 Hz interference or ground-loop noise has shown up as a recurring service call. It's not overkill for a clean commercial office rack — it's unnecessary there. Use it where the IG isolation and TAA compliance both add real value.
