12V fuse question

I am redoing the electrical in my 93 Toyota RV. I know enough about electrical to know I need to ask questions about all the things I do not know.

I picked up a WFCO NOS power/distribution panel without any paperwork. I am wondering what the 2 30 amp fuses are protecting? Anyone know??

    They are reverse polarity fuses. If battery is connected up wrong they will blow to protect the electronics in the converter.

    agreed with above - the circuit board even has them labeled reverse batt(ery) protection fuse

    Thanks for the responses, greatly appreciated. I knew there was some white stuff on the green, but could not read it. Got a magnifying glass and that's what it says.

    I will try to give you something more challenging next time. Thanks Jim

    Looking forward to the challenge - good luck with your wiring project :0

    If you have a smart phone, it makes a great magnifying glass - snap a picture and you can zoom way in :)
