The GTYE-16F is a 16 circuit flush mount load center purpose-built for small apartment buildings, mixed-use developments, and light industrial workshops. With capacity for a main breaker plus fifteen branch circuits, it enables dedicated power zones for multiple tenants or equipment areas - offering commercial-grade circuit density without oversizing the installation.

Description

This 16 circuit flush mount load center fills the gap between modest residential enclosures and large commercial boards, making it the natural choice for buildings where several independent zones - individual retail units, rental flats, or workshop bays - each require their own protected circuits. Its flush-mount chassis recesses cleanly into corridor or lobby walls, preserving finished aesthetics while protecting the door from impacts.

Constructed from 1.2–1.5 mm electro-galvanized steel with a durable powder coat, this 16 circuit flush mount panel resists corrosion and jobsite abuse. It accepts standard 1″ THQL breakers, includes full copper neutral and ground bars, and features knockouts on all six faces - delivering commercial-grade reliability in a space-efficient footprint.

FAQ

Q: When all 16 circuits are fully loaded, is heat dissipation uniform across the center area of the bus bar?

A: The GTYE-16F bus bar uses a symmetrical dual-row layout; current splits evenly from the central incoming terminal toward both sides. The center area runs approximately 3–5°C warmer than the outer ends, but remains fully within the IEC 61439-3 temperature-rise limit (≤ 60 K) at the 125A overall rating. Top and bottom ventilation gaps in the enclosure promote natural convection - no additional fan is required.

Q: Does the GTYE-16F door support padlocks or tamper-resistant latches?

A: The standard door latch is a spring-clip type. A padlock (shackle diameter ≤ 6 mm) can be added through the 6 mm hole provided next to the latch. For higher-security locations such as school corridors or hotel electrical rooms, an optional tamper-resistant hinge-lock kit is available to secure the door to the frame with a dedicated lock, preventing unauthorized access. Ensure the padlock or lock hardware does not interfere with proper door closure and sealing.

Q: Can photovoltaic inverters or energy storage batteries be directly connected to GTYE-16F?

A: It cannot be directly connected. The photovoltaic inverter outputs alternating current that is synchronized with the power grid. If it is directly connected to the distribution panel, during a power outage, it may send electricity back to the line, endangering the safety of maintenance personnel. The correct approach is to install a dedicated grid-tie disconnect switch upstream of the 16th floor and configure an island protection device. The energy storage battery needs to be connected through a bidirectional inverter, and all grid-connected equipment must comply with the interconnection standards of the local power company.

Q: What additional equipment is required for the backup generator to be connected?

A: A mechanical transfer switch (Manual Transfer Switch) or an automatic transfer switch (ATS) must be installed. It is strictly prohibited to switch between the grid and the generator by using double-pole cables or plugging/unplugging. The transfer switch should be located upstream of 16F to ensure that only one power source is connected to the panel at any time. Additionally, the neutral line grounding method of the generator must be compatible with the original grounding system of the building; otherwise, dangerous ground voltages may occur during the switching process.
