It provides the ultimate convenience by automatically managing the transition between shore power and your backup generator. Capable of handling generators up to \u003cstrong\u003e12kW\u003c\/strong\u003e, the PMTS-50 ensures your high-demand appliances—like dual AC units and electric water heaters—remain powered without the need for manual cord swapping.\u003c\/p\u003e\n\u003cp\u003eTo protect your expensive electrical equipment, the PMTS-50 includes an \u003cstrong\u003eintegrated 20-30 second time delay\u003c\/strong\u003e for generator startup. This allows the generator's engine and voltage to reach a stable operating state before the electrical load is applied, preventing damaging surges or frequency dips. This \u003cstrong\u003eETL Listed\u003c\/strong\u003e unit is built with safety as a priority, featuring a durable, high-impact enclosure and internal mechanical interlocks to prevent power backfeed.\u003c\/p\u003e\n\u003cdiv style=\"background-color: #f8f9fa; border-left: 5px solid #2e7d32; padding: 15px; margin: 20px 0;\"\u003e\n\u003cstrong\u003eSearch Summary:\u003c\/strong\u003e 50A \/ 120\/240VAC Rated | Supports up to 12kW Generators | 20-30s Stabilization Delay | ETL \u0026amp; FCC Certified | Heavy-Duty Relay-Based Design | Terminal Blocks for 6-14 AWG Wiring | 2-Year Warranty.\u003c\/div\u003e\n\u003ch3\u003eHigh-Capacity Performance Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic Source Prioritization:\u003c\/strong\u003e Intelligently senses available power.
