I'm making a basic ekeggle and I've got a question pertaining to the size of the SSR needed. I've been searching through HBT for ideas from other ekeggles and it seems that the general view on the board is to use an oversized SSR. I'll use myself as an example. I am installing a 5500W/240V heating element into the keggle and using an auber PID connected to a RTD sensor to monitor the temp(not needed for this question, just giving you a complete view of what I'm doing). Watts=Amps*Volts. Watts/Volts=Amps. 5500W/240V=22.917Amps. Why do I see everyone on the board purchasing and using 40A SSR units? One SSR can only control one mechanical object so why go overboard? If there is a valid reason, I would like to know before I purchase my SSR/heatsink. Thanks.
