Can I run AC and microwave on 30 amp?

Often no—that's 2,500–3,500W combined. Stagger use or add soft-start to AC. See load management checklist and 30 vs 50 amp guide.

What is 30 amp load limit?

30 amp = 3,600W total. AC alone ~1,500–2,000W running. Stagger AC with microwave and water heater. See our printable checklist.

🔎 30-Second Summary

The RV Electrical Load Management Checklist is designed to help RV owners manage their electrical load effectively, preventing issues such as overload, breaker trips, and voltage damage. It emphasizes the importance of staggering high-draw appliances and verifying voltage before usage, especially in RVs with 30-amp and 50-amp service.

Generated from this page. Always verify technical specs.

When to Use This Checklist

Printable Checklist — RV Electrical Load Management

30 Amp Load Limits (3,600W Total)

□ AC running: ~1,500–2,000W. Startup surge: 2,500–3,500W (or ~1,000–1,500W with soft start).
□ Microwave: 600–1,200W. Do not run with AC if near limit.
□ Water heater (electric): 1,300–1,400W. Stagger with AC.
□ Space heater: 1,500W. Stagger with AC.
□ Fridge, lights, TV: 200–400W combined.

Pre-Trip Load Check

□ Know your service: 30A (3,600W) or 50A (~12,000W)?
□ EMS or surge protector with voltage display in rig?
□ Verify voltage 108–132V before running AC. See test pedestal voltage.

Stagger Rule

□ On 30A: Run AC OR microwave OR water heater—not all at once.
□ Start AC first, let stabilize, then add smaller loads.
□ If breaker trips: reduce load, wait 2 min, reset once. If trips again → stop.

Generator Load (if applicable)

□ Generator sized for AC startup surge? See generator for 15K BTU AC.
□ Soft start reduces surge. See best soft start.
□ Use watts/amps calculator to verify.

Quick reference: 30A = 3,600W total. AC ~1,500W running. Stagger AC + microwave + water heater.
