The biggest influence is probably the serving utility’s metering compartment and underground pull-section dimensions. Guessing 208V 3ø, with four 90-amp furnace branch circuits. Each furnace: (25,000W/208V/1.732)*1.25 = 87 amperes… Rough guess 600A 300V class-T fused main and a 225A-bus panel/feeder for everything else.
