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.

3 tools expose this connector's capabilities to your AI agent.

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

Is a 20A breaker enough for a 1500W continuous load at 120V?

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.

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

The voltage drop is 1.25% with an end voltage of 118.5V.

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

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

Following NEC rules, the tool limits continuous load capacity to 80% of the breaker's rated amperage to prevent overheating.
