The Amana PSHW Series Commercial PTAC Disconnect Switch is a code-compliant power isolation module engineered to integrate directly inside Amana PTSB and PTCB series electrical sub-bases. Designed to satisfy National Electrical Code (NEC) regulations mandating an accessible, line-of-sight power disconnect switch at the HVAC unit, the PSHW series allows service technicians and hotel maintenance staff to safely de-energize the PTAC chassis without accessing the main building circuit breaker panel.

Configured for specific line voltages ( $208/230V$ or $265V$ ) and sub-base color schemes (Quiet White vs Black), the PSHW series mounts neatly inside the sub-base enclosure frame—delivering local high-voltage safety shutoff while maintaining a clean, cord-free room profile.

Code Compliance & Variant Selector: Essential for commercial hotel, multi-family, and healthcare projects where local electrical inspectors require a dedicated equipment disconnect switch. Select your exact line voltage ( $208/230V$ vs $265V$ ) and sub-base color match (Quiet White vs Black) from the variant dropdown options below.

Local High-Voltage Power Isolation for Technician Safety & NEC Compliance

In commercial lodging, healthcare facilities, and multi-family developments, local building inspectors strictly enforce NEC Article 440 requirements, which dictate that a dedicated line-of-sight electrical disconnect switch must be located within reach of motorized HVAC equipment. The Amana PSHW Series Disconnect Switch provides a pre-engineered, factory-certified solution that installs directly inside the PTAC sub-base frame.

Integrated Sub-Base Mounting & Concealed Safety Engineering

Built-In Sub-Base Enclosure Fit: The PSHW module mounts behind the sub-base access cover plate, providing immediate, tool-accessible power isolation for service staff without exposing raw line-voltage wiring to room occupants.
Slashes Maintenance Turnaround Time: Enables engineering teams to instantly isolate individual PTAC units for filter changes, coil cleanings, or chassis replacement without stepping out of the room to search for main breaker panels.
Universal Sub-Base Compatibility: Engineered for direct fitment into all Amana PTSB and PTCB commercial steel sub-bases across 15A, 20A, and 30A circuit configurations.
Heavy-Duty Commercial Rocker Assembly: Heavy-gauge double-pole commercial switch mechanism built to withstand repeated high-voltage switching without contact pitting or mechanical wear.

Heavy-Duty Commercial Double-Pole Switch: Rated for high-voltage commercial inductive and resistance heating loads.

Custom Sub-Base Faceplate Included: Comes with color-matched mounting faceplate and switch guard hardware.

Direct Plug & Terminal Connections: Pre-wired wire leads simplify line-voltage connection inside the sub-base junction box.

Universal PTSB / PTCB Sub-Base Mounting: Fits all standard 42-inch Amana commercial electrical sub-bases.

Clear ON/OFF Safety Marking: Prominent visual indicators show power status at a glance.

Frequently Asked Questions

Q1: What is the purpose of the Amana PSHW disconnect switch kit? +

A: The PSHW switch is a local power disconnect module that mounts inside an Amana sub-base (PTSB or PTCB series). It provides a dedicated, accessible switch to shut off high-voltage electricity directly at the PTAC unit to meet local electrical codes and ensure technician safety during maintenance.

Q2: Is the Amana PSHW disconnect switch required for all PTAC installations? +

A: While not required in every single residential layout, local commercial building codes and National Electrical Code (NEC) rules often mandate a local line-of-sight disconnect switch within sight of commercial HVAC equipment in hotels, apartments, and healthcare facilities.

Q3: Which PSHW variant do I need for a Black sub-base? +

A: For any Black sub-base (such as PTSB320BK, PTSB330BK, PTSB420BK, or PTSB430BK), order the PSHW0304BK variant. It features universal voltage compatibility (208/230/265V) with a matching Black faceplate.

Q4: Where is the PSHW switch mounted on the sub-base? +

A: The PSHW switch mounts directly into the pre-punched knockout slot on the front or side cover of the Amana PTSB or PTCB sub-base enclosure, keeping wiring concealed inside the steel housing.

Q5: Can the PSHW disconnect switch be installed on a 265V PTAC unit? +

A: Yes. For 265V Quiet White sub-bases, specify the PSHW04A model. For 265V Black sub-bases, specify the PSHW0304BK model.
