# Electrical Load Calculator MCP for AI Agents MCP

> The Electrical Load Calculator MCP determines the exact power requirements for any room, circuit, or panel. It helps electrical engineers and building professionals size panels correctly by calculating total wattage from lights, wall outlets, and fixed appliances. You'll determine safe current draw and check if a circuit adheres to NEC standards before laying wire.

## Description

Designing an electrical system is complicated; you can't just eyeball the power needs. This MCP lets your AI client calculate exactly how much electricity any space or group of fixtures will consume, ensuring you don’t undersize a panel or risk overloading a circuit. Instead of cross-referencing multiple code books and doing manual math for every room, you feed the details (room size, fixture count, appliance type) to your agent. It runs those numbers instantly, checking against safety rules like the 80% breaker capacity rule. When you connect this through Vinkius, your AI client gets access to professional-grade tools that suggest appropriate wire gauges and breaker sizes based on current NEC standards. You get precise electrical load calculations without leaving your chat interface.

## Tools

### lookup_appliance_impact
Retrieves the required wattage and peak power consumption numbers for fixed appliances like water heaters or HVAC units.

### evaluate_circuit_safety
Checks if an existing circuit load is safe, comparing it against the 80% breaker capacity rule, and recommends necessary hardware upgrades.

### calculate_receptacle_load
Estimates the total VA load that a group of wall outlets can safely handle for general-purpose circuits.

### get_lighting_load
Calculates the required electrical demand based on a room's dimensions and its intended use (e.g., kitchen, bedroom).

## Prompt Examples

**Prompt:** 
```
What's the minimum power needed for a 30x12 ft master bedroom?
```

**Response:** 
```
**Lighting Load Calculation**

Based on standard residential density (assuming recessed lighting):
*   Room Type: Bedroom
*   Area: 360 sq ft
*   Required Wattage: **720 Watts**

This estimate is based on a minimum of 2.0 W/sq ft for optimal ambient light.
```

**Prompt:** 
```
I have three kitchen outlets and one dishwasher. What's the total load?
```

**Response:** 
```
**Load Summary (VA)**

*   Receptacle Load (3 Outlets): 750 VA
*   Dishwasher Unit: 1200 VA (Peak)
*   **TOTAL ESTIMATED LOAD:** **1950 VA**

This total requires a minimum of a 20 Amp circuit.
```

**Prompt:** 
```
Is a 15A breaker safe for a 1400W load at 120V?
```

**Response:** 
```
⚠️ **Circuit Status: OVERLOADED**

The proposed current draw is calculated at **11.67 Amps**. This exceeds the safe operating threshold of 12 Amps (80% capacity for a 15A breaker).

**Recommendation:** Upgrade to a minimum 20 Amp breaker and check wire gauge.
```

## Capabilities

### Calculate total lighting demand
Determine the required wattage for fixtures in a specific room type, considering its area.

### Estimate outlet power consumption
Calculate the combined VA load from a specified number of general wall receptacles.

### Determine appliance power draw
Find both the running and peak wattage requirements for specific, fixed appliances in your build.

### Verify circuit safety compliance
Check if a proposed load exceeds safe limits and recommends necessary hardware upgrades like breakers or wire gauge.

## Use Cases

### Sizing a new commercial kitchen panel
A project manager needs to know if their main electrical service is big enough for new appliances. They prompt the agent with appliance specs and room size, using lookup_appliance_impact alongside get_lighting_load to confirm the entire system can be powered safely.

### Checking existing residential circuit safety
A homeowner is worried about an old breaker. They input the current load and breaker specs, letting evaluate_circuit_safety tell them if the wiring or breaker needs to be upgraded before they plug in a new unit.

### Designing bathroom receptacles
An architect must confirm enough power for multiple outlets. They use calculate_receptacle_load, specifying the number of outlets and their type, getting an immediate VA estimate to pass to the electrical design team.

### Calculating load density per square foot
An engineer needs to determine optimal lighting requirements for a large office space. They use get_lighting_load by inputting the room's dimensions, receiving a clear wattage requirement based on industry standards.

## Benefits

- Avoid costly site errors. Use evaluate_circuit_safety to check if current loads exceed the 80% safety threshold, guaranteeing your design meets code.
- Instantly calculate room power needs. The get_lighting_load tool figures out exact wattage based on square footage and intended use, eliminating guesswork for every space.
- Accurately size outlet circuits. Run calculate_receptacle_load to estimate the total VA load for groups of wall outlets in a single prompt.
- Account for major fixed items. lookup_appliance_impact finds both running and peak power draw for specific appliances, ensuring you don't forget high-draw equipment.
- Know your wire gauge upfront. The MCP suggests appropriate breaker and wire sizes immediately after calculating the load, saving time in material ordering.

## How It Works

The bottom line is you get an instant, code-compliant estimate of every electrical load needed for your project.

1. Provide the AI agent with the specific parameters of the installation, such as room dimensions (e.g., '200 sq ft kitchen') and fixture counts.
2. The MCP processes this data using specialized electrical formulas to calculate component-specific loads (lights, outlets, appliances).
3. Your agent receives a final report detailing the total required wattage, confirming if it meets code standards, and suggesting optimal breaker and wire sizing.

## Frequently Asked Questions

**How do I use the Electrical Load Calculator MCP to size my main panel?**
You provide the agent with all major room loads, appliance specs, and total area. The MCP consolidates this information, ensuring every fixture and unit contributes accurately to a single, code-compliant total for your main service entrance.

**Does the Electrical Load Calculator MCP account for breaker safety rules?**
Yes. It checks loads against industry standards, specifically verifying if circuits adhere to the 80% capacity rule before recommending hardware. This prevents costly overloads and fire hazards.

**What kind of information do I need for appliance load lookup?**
You need the specific name or type of fixed appliance (like a water heater) and its known running wattage, so the MCP can retrieve both its continuous and peak power draw requirements.

**Can this tool calculate lighting needs for commercial vs. residential?**
Yes. The get_lighting_load function accepts room type (e.g., 'Kitchen' or 'Office') so the calculation uses the correct wattage density per square foot, giving you an accurate estimate regardless of scale.
