1. What is an RV Electrical Load Calculator?

Definition: This calculator determines the total electrical load in kilowatts (kW) by summing the power consumption of all appliances in an RV.

Purpose: Helps RV owners and campers ensure their electrical system can handle all connected devices without overloading.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Total electrical load (kilowatts)
• \( P_{load} \) — Power of individual appliances (watts)

Explanation: Each appliance's wattage is converted to kilowatts (divided by 1000) and then summed to get the total load.

3. Importance of Electrical Load Calculation

Details: Proper load calculation prevents circuit overloads, ensures generator compatibility, and maintains electrical system safety.

4. Using the Calculator

Tips: Enter the wattage for each appliance you plan to use simultaneously. Leave unused fields blank or zero.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical RV electrical capacity?
A: Most RVs have 30-50 amp service (3.6-6 kW for 120V systems), but check your specific RV's electrical panel.

Q2: Should I include all appliances?
A: Only include those you'll use simultaneously. Some appliances like A/C have high startup surges.

Q3: How do I find appliance wattage?
A: Check labels, manuals, or use a watt meter. Typical examples: LED lights (10W), fridge (150W), A/C (1500W).

Q4: What if my total exceeds my RV's capacity?
A: Consider staggering use of high-wattage appliances or upgrading your electrical system.

Q5: Does this include 12V systems?
A: No, this calculates 120V AC loads only. For 12V DC systems, use a different calculator.
