# Industrial Specification: Power Switchboard

## 1. Technical Definition
A centralized electrical distribution panel that controls and protects power circuits within a power management system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **400-690 V AC, 50-60 Hz, 0-40°C ambient temperature**. Failure boundary: **Insulation breakdown at 2.5 kV/mm dielectric strength, busbar thermal deformation at 105°C, contact erosion at 100,000 operations**, Mechanism: **Dielectric breakdown per Paschen's Law (pd=7.5×10^5 V·m^-1·Torr^-1), Joule heating (P=I²R), arc erosion per Richardson-Dushman equation**.

### 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.
