I had open breaker space in the power panel of the garage, so the decision to install a 240V 50 amp breaker to support the Grizzl-E EV charger seemed a no brainer. Could have hard wired the charger to the breaker but I need to keep an outlet available for the MIG welder. Wired a NEMA 14-50 outlet to the breaker to accept the 'no frills, no bells, no whistles' Grizzl-E charger and changed out the plug for the welder for multi use approach to the outlet, leaving the charger DIP switches to the 40 amp setting. The Solterra claims to use 27 amps max, but I found out differently using an ammeter after install and verified its pulling 29.7 amps (both black and red leads). Being paranoid, I checked the breakers, plugs, and cables for temperature 'excursions'. The 50 amp breaker was warm and emitting a little bit of humming noise (light arching) which was rectified by reseating the breaker. Noise gone, no more heat, happy install! Really can't beat the cost or the quality of the Grizzl-E 'dumb' charger, and they aren't built in China (Go Canada!).
