inline AC ammeter

[mjf]

When installing an inline AC ammeter do I need a shunt?

I don't believe I do, but not certain.

20 amp circuit supplying backup power to an inverter.

normally there is zero amps. when activated the amp draw will be between 150mA and 200mA.

I bought an inline 300mA AC ammeter and planned to feed the hot directly through it.

any problem?

Sounds good to me.

The Current Transformer is what you would shunt if you took the meter off. No CT, no shunt.

It really depends on the meter...internally or externally shunted, or even CT.

Thanks.
