A mid-size restroom trailer with 2-4 stalls typically draws 15 to 30 amps total, similar to a residential kitchen appliance. The trailer's electrical load comes from interior lighting, an exhaust fan, and sometimes a small water pump or heater.
You must provide a dedicated 20-amp circuit for the trailer. Plugging it into a shared circuit with other event equipment like catering warmers or a DJ's speakers can trip the breaker. Confirm with the venue that they can supply a dedicated outdoor-rated outlet near the planned placement location. The trailer also requires level ground to function properly.
For a fall wedding, the main seasonal consideration is the overnight temperature. If it drops near freezing, the trailer's fresh water tank and plumbing could be at risk. Some operators will winterize the unit with antifreeze if cold weather is expected, but this is a service to discuss with your rental company. Since your event is in October 2026, confirm the power requirements with the specific trailer model you choose well in advance of the wedding.
