Soalar panel junction box re-designed - 2011

 We did some more solar panel(SP) wiring and it became apparent that the junction box that we got from Home Depot(HD) was not going to work well for this much and size of wire. It could work but we would like something nicer.

December 2011  - Currently At Marina Cortez Harbor Island, San Diego, CA

We tried to wire in the 4 AWG cable from Marine Exchange but it was too much wire for this size box. We drilled a new hole into the box and tried it out. I got jabbed a bunch of times with the stripped wire but made it through😏

 We picked up a 150 amp Blue Sea Systems duel buss from Marine Exchange with 1/4 inch studs and some terminal ends and heat shrink. 

 Marine Exchange has some Ancor marine heat shrink which has glue in it and is a nice option. It can be put over the terminal ends after they are installed so that eliminates forgetting to slide it on before installing the terminal ends. It is a little thicker than the HD type and I pressed it against the terminal end where it did not shrink up close enough and the glue held it in place as it cooled.

  So it was that we re-stripped the SP #10 wires and put on the terminal ends for #10 screws that go onto the buss. The only dray back is the buss with the wires sticking out the sides takes up a bigger footprint.

We also will need to make some sort of shield so dripping condensation will not get into the buss. I think that probably would not happen but we will be safe on this one. The old junction box may serve this purpose by cutting it up. This is getting mounted on the storage side of the lazarett because of space considerations.

 We took the 4 AWG wires and tested them in the soplar controller to make sure they fit in the connectors and they do. The next thing to do is measure the length of wire from the buss to the controller and get the 4 AWG cable and connectors with heat shrink installed on them.
