Here in the US, a normal wall receptacle circuit is rated 15 amps max at 120 volts for short term. To meet UL listing, the total item (s) being plugged in can not be over 1500 watts rating I believe. The vac has a power draw rating around 1000 watts leaving 500. In reality, the vac does not draw 1000 watts continuous. My CT33 with my 15 amp rated miter saw plugged in does not trip a 15 amp breaker. Power tools are labeled with absolute max power draw and normally only draw that on powerup.
