Middle Atlantic PET Bp-cs-fd EWR & DWR - PET-K-D/EWRD

Middle Atlantic PET-K-D/EWRD Protective Earth Terminal Kit for EWR and DWR Series Racks

Overview

The Middle Atlantic PET-K-D/EWRD is a bonding kit purpose-built for grounding conductive surfaces on EWR and DWR Series wall mount racks. If you're commissioning an EWR or DWR enclosure in a commercial installation and need to satisfy NEC or local code requirements for protective earth bonding — this is the part that closes that gap. It ships ready to install: a pre-terminated 12 AWG bonding wire, six inches long, with a #10 ring terminal on one end and a male disconnect on the other. No field fabrication, no guessing at gauge. The PET-K-D/EWRD (often searched as PET K D/EWRD) is a direct, code-supporting answer to the grounding step that installers sometimes improvise at the last minute.

Wall-mount rack enclosures carry a real grounding obligation once they're loaded with active equipment — switches, power distribution units, or NVRs all introduce fault-current paths through the chassis. A proper bonding conductor with the right termination hardware is what keeps that fault current on a controlled path rather than through unintended routes. This kit provides that conductor in a verified gauge and length, matched to the Middle Atlantic EWR and DWR platform.

Key Features

• 12 AWG Bonding Wire: 12-gauge conductors comfortably handle the fault-current bonding requirements typical of low-voltage rack equipment. Heavier than many field-improvised solutions, it meets the bonding conductor sizing that inspectors look for in commercial enclosure installs.
• Pre-Terminated #10 Ring Terminal: The #10 ring terminal on the rack-side end connects securely to standard M5 and #10-32 bonding studs common on EWR and DWR enclosures — no stripping, crimping, or sourcing terminals separately on the job site.
• Male Disconnect on the Other End: The male disconnect termination mates with the corresponding female disconnect point in the EWR/DWR rack system, keeping the bonding connection positive and removable for service without cutting the wire.
• Six-Inch Conductor Length: At 6 inches, the wire is long enough to route cleanly to the enclosure bonding stud from typical termination points without excess slack bunching inside the rack — a small detail that matters in tight wall-mount enclosures where cable management is constrained.
• Series-Specific Fit: Designed explicitly for EWR and DWR Series racks. If you're working with a different Middle Atlantic enclosure family, verify the bonding hardware before ordering — a mismatched termination defeats the purpose of a pre-terminated kit.
• Compact, Lightweight: At 0.2 lbs and packaged in a 9.5 x 7.0 x 0.5 inch envelope, the PET-K-D/EWRD ships flat and stores easily in a job box. Order one per enclosure as a routine line item alongside the rack itself.

Integration and Compatibility

The PET-K-D/EWRD is matched to the Middle Atlantic EWR and DWR Series wall mount rack platform. These enclosures are widely used in commercial AV, surveillance, and network distribution applications where a rack accessory like this bonding kit is part of a complete, code-compliant installation. If you're building out a structured wiring or security head-end in a retail, education, or enterprise environment using EWR or DWR enclosures, add this kit at the time of rack procurement — it's a low-cost item that prevents a last-minute trip back to the supply house before inspection.

This kit does not apply to Middle Atlantic's other enclosure lines (RK, ERK, BGR, or similar series). For those platforms, consult the appropriate bonding hardware from the Middle Atlantic rack accessories line. If you're pairing this enclosure with active equipment like network video recorders or PoE switches, ensure the enclosure itself is properly grounded to building ground before energizing the equipment — the PET-K-D/EWRD is the termination hardware for that connection, not a substitute for a facility ground path. For broader rack planning, a rack power and accessories guide can help you identify all the infrastructure components needed for a complete head-end build.

Frequently Asked Questions

Q: Which Middle Atlantic rack series is the PET-K-D/EWRD compatible with?

A: The PET-K-D/EWRD is designed specifically for Middle Atlantic EWR (Enclosed Wall Rack) and DWR (Durable Wall Rack) Series enclosures. It is not listed as compatible with other Middle Atlantic rack families such as RK or ERK series — verify your enclosure model before ordering.

Q: What wire gauge does the bonding wire use, and how long is it?

A: The bonding wire is 12 AWG (12-gauge) and six inches in length. It ships pre-terminated with a #10 ring terminal on one end and a male disconnect on the other — no field termination required.

Q: Do I need one kit per rack enclosure?

A: Yes. Each PET-K-D/EWRD provides a single bonding wire assembly. Order one per EWR or DWR enclosure that requires a protective earth bonding connection.

Q: Can I use this kit to ground equipment inside the rack, or is it for the enclosure chassis only?

A: The PET-K-D/EWRD is a chassis bonding kit — it bonds the conductive surfaces of the EWR or DWR enclosure itself to the protective earth point. Equipment grounding within the rack is handled separately through each device's power connection and any supplemental PDU or rack-mount power distribution hardware.

Q: Is the PET-K-D/EWRD a rack-mount or wall-mount product?

A: The EWR and DWR Series it serves are wall-mount rack enclosures, so the PET-K-D/EWRD is used in wall-mount rack installations. The kit's own mounting classification is listed as rack mount, consistent with its use inside the enclosure.

The detail that catches integrators off-guard on EWR and DWR Series installs is the chassis bonding step — it's easy to treat it as optional until an AHJ flags it at inspection. The PET-K-D/EWRD resolves that with a pre-terminated 12 AWG wire assembly that goes in without any field fabrication, specifically sized and terminated for this rack family.

Technical Highlights:

• 12 AWG conductor: Heavier gauge than improvised field solutions; comfortably satisfies bonding conductor sizing expectations for commercial enclosures carrying active low-voltage equipment.
• Pre-terminated ends: #10 ring terminal on one end, male disconnect on the other — both ends are done. No crimping tools, no sourcing ring terminals separately, no guesswork on stud sizing for EWR/DWR bonding points.
• Six-inch length: Short enough to route cleanly inside a compact wall-mount enclosure without creating slack management problems, long enough to reach the bonding stud from any standard termination point in the EWR or DWR chassis.

Deployment Considerations:

• Order one PET-K-D/EWRD per EWR or DWR enclosure at the time of rack procurement — it's a 0.2 lb line item that's easy to forget until you're on site and the AHJ is walking the install.
• This kit is series-specific: it is not interchangeable with bonding hardware for other Middle Atlantic enclosure families. If your project mixes EWR/DWR with RK or ERK enclosures, source the appropriate bonding kit for each series separately.

The PET-K-D/EWRD belongs on every EWR and DWR Series rack order in commercial environments — education, enterprise, retail — where inspections are part of the commissioning process and chassis bonding is a line item on the punch list, not an afterthought.
