Briefly drawing more power would not really be an issue. Circuit breakers don’t operate as binary devices in the sense that a 15A breaker works indefinitely at 14,999mA and then turns off at 15,000mA. They usually use a bimetallic strip to provide a gradual response (more current = more heat = faster trip) with an electromagnet actuated trip that creates an absolute limit. See, for example, this PDF: https://download.schneider-electric.com/files?p_enDocType=Data+Bulletin&p_File_Name=0600DB0105.pdf&p_Doc_Ref=0600DB0105 https://download.schneider-electric.com/files?p_enDocType=Da... Even at double the rated current you’re looking somewhere around 30-90 seconds before it trips. If this weren’t the case, we’d be tripping breakers every time we fired up a stand mixer or a vacuum cleaner.
