All right, let's count them up:
1 The use of copper and aluminum conductors on the same lug. ( nice case of future electrolysis )
2 Lack of anti-oxidant on the aluminum conductors.
3 Using the utility company's post to attach all the items.
4 2" pipe too crowded, you would need a good 30% max. of conduit fill.
5 The use of "Silicone like substance".
6 100 amp breaker protecting what looks like a # 12 or # 14 going to another fuse.
7 Lack of waterproof connectors on the pipes.
8 Lack of "workman like manner" to install all these items.
