    • Only 125 VDC in.

Voltages

  • 1000V for this one - [3]
  • Why are others limited to 250V? Because the circuit breaker is 250V - [4]
  • Go to Midnite for higher V combiners? [5]
  • Most fuse holders are rated for 600-1000V, while DC breakers are 150V [6]
  • Check.pngWith 600VDC YRSP-D2 [7] circuit breaker - [8]. Combined wire is fatter, at least 10 ga. Circuit breaker appears to be 600Vdc rated [9].
  • Check.png500VDC - [10]. Combined output appears to have 12 ga wire, or 20A max. Would need 10 ga for 30A combined output, so this is really only good for 20A.

Fuses
