50A to 30A Splitter with Overload Protection: Your Reliable Power Adaptation Partner

　　In scenarios like RV camping, outdoor power supply, or home appliance temporary wiring, you may often face a common dilemma: the power source provides a 50A interface, but your device only supports a 30A input. A mismatched current interface not only blocks power access but also risks equipment damage or electrical hazards if forced to connect. The 50A to 30A Splitter with Overload Protection solves this pain point perfectly—it bridges the current gap between the power source and devices while adding a critical safety barrier, making power adaptation efficient and secure.

　　I. Core Function: Bridging Current Gaps, Guarding Power Safety

　　This splitter is designed to convert a single 50A male power plug into one or more 30A female sockets (common configurations: 1-to-1 or 1-to-2), enabling 30A-rated devices (such as RV air conditioners, camping refrigerators, electric grills, or home large-scale water heaters) to safely draw power from 50A power sources.

　　Its biggest advantage lies in the built-in overload protection module—a "safety valve" for power use. When the actual current drawn by the connected device exceeds 30A (the rated current of the splitter) or the total power exceeds the safe threshold, the protector will automatically cut off the circuit within 0.1 seconds. This prevents overheating of wires, melting of terminals, or even short circuits and fires caused by overload, effectively protecting both the splitter and your valuable devices.

　　II. Key Features: Safety, Durability, and Versatility

　　1. Overload Protection: Multi-Level Safety Design

　　Precise Trigger Threshold: Calibrated to 30A±5% rated current—neither too sensitive (avoiding false tripping during normal power fluctuations) nor too slow (preventing delayed protection).

　　Manual Reset Function: After an overload occurs, simply press the reset button on the splitter to restore power (no need to replace fuses, saving time and cost).

　　Visual Indication: Equipped with a LED power light and overload warning light—green for normal power supply, red for overload shutdown, allowing you to quickly identify the working status.

　　2. High-Quality Conductive Materials: Low Loss, High Heat Resistance

　　Copper Core Wires: Adopts 10AWG (American Wire Gauge) tinned copper wires—tinned coating prevents oxidation and corrosion, ensuring stable current transmission (current loss ≤2% during long-term use).

　　Gold-Plated Terminals: The plug and socket terminals are gold-plated, reducing contact resistance and avoiding overheating caused by poor contact (can withstand high temperatures up to 105℃ without deformation).

　　Flame-Retardant Shell: Made of PC+ABS fire-resistant plastic (meets UL94 V-0 flame retardant standard)—self-extinguishes within 10 seconds if exposed to open fire, preventing fire spread.

　　3. Universal Compatibility: Fits Multiple Scenarios

　　Interface Standards: Complies with NEMA (National Electrical Manufacturers Association) standards—50A male plug (NEMA 14-50P) and 30A female socket (NEMA TT-30R), compatible with most North American RVs, camping equipment, and home appliances.

　　Weatherproof Design (for outdoor models): The shell is IP44 waterproof—resistant to splashing water, dust, and UV rays, suitable for outdoor use in RV parks, campsites, or construction sites (note: not for submersion in water).

　　III. Applicable Scenarios: Where You Need It

　　1. RV and Camping Trips

　　RV parks often provide 50A power stations, but many RV internal devices (e.g., 15,000 BTU air conditioners, electric stoves) use 30A interfaces. This splitter allows you to connect multiple 30A devices to a single 50A source (e.g., 1-to-2 models support simultaneous use of air conditioners and refrigerators) without worrying about overload.

　　2. Home Appliance Temporary Wiring

　　When using high-power home appliances (e.g., electric water heaters, induction cookers) that require 30A current, if the home only has a 50A industrial socket (common in garages or balconies), this splitter can safely adapt the current, avoiding the need to modify the home wiring.

　　3. Outdoor Events and Construction Sites

　　For outdoor events (e.g., food trucks, temporary stalls) or construction sites, 50A power sources are often used for heavy equipment. This splitter enables 30A small devices (e.g., electric fans, power tools) to share power, improving the utilization of power sources.

　　IV. Usage Notes: Ensure Safe and Correct Use

　　Check Ratings Before Use: Confirm that the power source’s voltage (120V/240V) matches the splitter’s rated voltage (do not use 240V power sources with 120V-only splitters).

　　Avoid Overloading: Do not connect devices with a total power exceeding 3600W (for 120V systems) or 7200W (for 240V systems)—calculate the total power of connected devices in advance (power = voltage × current).

　　Secure Connections: Insert the plug fully into the socket to ensure tight contact (loose connections may cause arcing and overheating).

　　Regular Maintenance: Every 3–6 months, check the wires for cracks, the terminals for oxidation, and test the overload protection function (can simulate overload by connecting a high-power device temporarily to confirm whether the protector trips).
