AC Power Requirements

The Strata CT requires a single-phase, 50/60 cycles power source of 240VAC, on a dedicated
20 ampere circuit breaker.
It is recommended that a dedicated AC service panel be used for the Strata CT. AC outlets,
must be dedicated to Strata CT use, fused, and grounded. Equipment unrelated to the Strata
CT must not be connected to the circuit or service panel dedicated to the Strata CT.
