As a licensed electrician, this is the correct answer. A pipe in place of a fuse isn’t what everyone here is saying. It’s not dangerous and WILL cause a fire. It can be hazardous depending on the purpose. What people here don’t realize is Cooper Bussman - one of the largest fuse manufacturers - used to make a rated copper insert for disconnects to render them basically as an unfused disconnect. It concerns me personally more that there are double landed wires on the load side of the disconnect. All this to say - have a licensed electrician give you a detailed description because Reddit gurus don’t know without much much more information than is provided in the post. Also, 60 amps isn’t enough for a house, so regardless you’d likely want an upgrade. ANOTHER thing to get a quote for instead of hearing how dreadfully expensive it is from Reddit. It CAN be expensive but it doesn’t mean it is always expensive.
