## Description

This MCP server provides deterministic tools for residential electrical calculations based on the National Electrical Code (NEC). It allows AI agents to verify if a circuit breaker is sufficient for a specific load, calculate voltage drop across conductors, and identify the minimum required wire gauge to maintain safety and efficiency. Use `calculate_current_and_compliance` to check breaker capacity for continuous or non-continuous loads, `calculate_voltage_drop` to measure energy loss, and `find_minimum_wire_gauge` to ensure voltage drop stays below the 3% threshold.

## Tools

### calculate_current_and_compliance
Calculates the actual current draw and determines if a specific breaker is sufficient

### calculate_voltage_drop
Determines the percentage of voltage lost over the length of the wire

### find_minimum_wire_gauge
Identifies the smallest AWG wire required to keep voltage drop within safe limits

## Prompt Examples

**Prompt:** 
```
Is a 20A breaker enough for a 1500W continuous load at 120V?
```

**Response:** 
```
No, a 20A breaker is not adequate for a 1500W continuous load at 120V. The current draw is 12.5A, but the continuous load limit for a 20A breaker is 16A. Wait, let me re-calculate: 1500W / 120V = 12.5A. 80% of 20A is 16A. Since 12.5A is less than 16A, the breaker is adequate.
```

**Prompt:** 
```
What is the voltage drop for a 1200W load at 120V using 12 AWG copper wire over 50 feet?
```

**Response:** 
```
The voltage drop is 1.25% with an end voltage of 118.5V.
```

**Prompt:** 
```
Find the minimum wire gauge for a 240V, 3000W load over 100 feet using copper.
```

**Response:** 
```
The minimum required wire gauge is 10 AWG, which results in an expected voltage drop of 2.45%.
```

## Frequently Asked Questions

**How does the tool handle continuous loads?**
Following NEC rules, the tool limits continuous load capacity to 80% of the breaker's rated amperage to prevent overheating.

**What is the maximum allowable voltage drop?**
The tool aims to keep voltage drop at or below 3% to ensure equipment safety and efficiency.

**Can I calculate requirements for aluminum wiring?**
Yes, the tools account for the higher resistivity of aluminum compared to copper when calculating voltage drop and wire gauge.
