➀ The ACA-20PC-1-AC1-RL and ACA-20PC-2-AC1-RL have 4-position on-board
➁ Specifi ed full-scale currents are those passing through the built-in CT's
➁ For the ACA-20PC-2-AC1-RL, if the load is connected to the meter's on-board
➃ All specifi ed maximum power supply currents are steady-state values.
➄ Maximum reverse polarity protection on "DC1" models is –40Vdc.

primary(load) circuit, over the frequency of 45-450Hz. The Overcurrent Rating
is a continuous rating that applies to the measured ac load current. It does
not apply to any circuitry external to the meter. Accuracy is guaranteed to the
rated current.
4-position terminal block, the 20A full scale range requires 12AWG solid
copper wire on all connections. If 14AWG solid copper wire is used, the current
should be limited to 15A. See Figure 3.
AC-powered models can draw higher surges at initial turn-on.
