Nice, im a beginner at this, (forgive me if wrong) but isn't that 236V ?

No, your seeing 236v spike because the voltage is unstable at the start. It soon goes to 120 volts PEAK. However the PEAK value is not the correct value for a 120 volt circuit, because voltage is rated in RMS rather than PEAK.

A 120 volt outlet has a peak voltage of 170. The peak value is found by multiplying 120*1.414 to get 170 volts peak.
