I have a question on the disconnect. I have a photo of this if I can upload it somewhere to make it easier to see as I am not technical at all!
We just had a disconnect hooked up with the main power outside out house, as the house is old, it could not be hooked up inside and could not replace the original panel from the 50s. So the power is hooked up, everything looks good, but the power line going from the disconnect into the house is enclosed in a casing, the casing is sloped away from the house and looks cockeyed and not as pleasing as it was straight. I was told this is in case of condensation but other houses seem to have it straight. This is more of a cosmetic issue than a real issue, but little thing’s bug me a lot. Also the casing did not cover the last 6 inches of the disconnect pipe, I was told this is because the casing cannot fit like that as it can’t bend, so the space is there showing the cable outside the casing. If I could upload a photo it would make more sense. thanks for any input.
