Yurtle,Sorry, but you cannot series connect NSTs, because practically all of them have center tapped secondaries which are connected to the cases. You would see voltage equal to the sum of half of the two secondary voltages between the two cases.
Paralleling them is fine, series connecting them will not work. Dave On 4/7/2015 1:17 PM, Yurtle Turtle via Tesla wrote:
There's no reason both NSTs have to be paralleled on a single 120 volt circuit. If you have 240 volts or can buy a breaker and run a circuit, you can run the two NSTs in series, but you'll have to rephase the secondaries.
