Hi Dick,
3x35A is a 230/400V 25KW inlet.
For 40KW 63A fuses are to be installed, mine are 80A
### whoa. 35 A x 400 V = 14 kw per phase. x 3 phases = 42
kva.
### To get 25 kw out [assuming 67 % eff on the lower bands]
25,000/ .67 = 37,323 watts of DC input. = 37.323 x 1.21 = 45.149
Kva.

Subject: Re: [ham_amplifiers] Re: 3 - phase HV supply
Euro 175.- to get concerted from single phase service to 3 phase
service in
the Lowlands. For that money you'll get:
3 fuses
a new 3 phase digital power/kWh meter
3 x 35 amps @ 400 VAC ( 42 kW AC, gud for 25 kW RF output ) = the
same
monthly fee compared to single phase service.
