Test Switch Adapters for the 6330 (290)
Bring Test Switch Functionality to Sites That Don’t Have One
TESCO’s Test Switch Adapters provide a safe and portable way to test transformer-rated meter sites that lack an installed test switch. Designed to work with the TESCO 6330 Meter Site Analyzer, these adapters plug directly into the meter socket, instantly creating a test-ready interface.
TESCO’s Test Switch Adapters offer utilities and field crews a plug-and-play alternative for transformer-rated meter sites where permanent test switches were never installed. Each model replicates the appropriate terminal layout for specific meter forms—allowing you to safely run accuracy, burden, and in-service tests with the TESCO 6330.
No test switch? No problem. TESCO brings the interface to you.
