Common Concerns Answered
Is this switch overkill for my smaller boat's power needs?
While a lower amperage switch might suffice for some, the Newmar SS Switch's 63A rating ensures robust performance and long-term reliability, preventing potential overload issues and protecting your investment in electrical equipment, even if your current needs are lower.
What makes this switch so expensive?
The price reflects the switch's superior construction, including heavy-duty contacts and a positive step cam mechanism, along with its higher 63A rating and cUL certification, all designed for maximum safety and longevity in demanding marine environments.
How does this switch prevent damage to my equipment?
This switch is specifically designed to isolate each AC power source (shore, generator, inverter). By ensuring only one source is connected at a time, it prevents hazardous backfeeding and potential damage that can occur when multiple AC sources are inadvertently connected simultaneously.
