# Industrial Specification: Central Control Cabinet

## 1. Technical Definition
The central control cabinet is the electrical and control hub of the Aluminum CNC Machining Cell, housing the primary control systems, power distribution units, and safety devices.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **24-48 VDC for control circuits, 400-480 VAC 3-phase for power circuits, 0-60°C ambient temperature**. Failure boundary: **Control voltage drops below 21.6 VDC for &gt;100ms, power voltage exceeds 528 VAC peak, ambient temperature exceeds 70°C for &gt;30 minutes**, Mechanism: **Semiconductor junction breakdown at 1.5× rated voltage (Paschen's Law), thermal runaway in power transistors at 150°C junction temperature, insulation breakdown at 3 kV/mm dielectric strength**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$  
> **Engineering Impact**: Governs heating element sizing for shrink tunnels/sealers.
