Control box for generator set

A control box for a generator set, comprising:

• a support structure configured to be mounted to a rail, wherein the support structure comprises:
• a first planar panel configured to be mounted to the rail;
• and
• a second planar panel offset from the first planar panel and configured to be mounted to the rail;
• a side planar panel configured to be connected to the first planar panel and the second planar panel;
• and
• an upper support structure perpendicular to the side planar panel and configured to be connected to the first planar panel and the second planar panel;
• wherein the upper support structure comprises a first trapezoidal unit having a first base and a second trapezoidal unit having a second base, wherein the first trapezoidal unit and the second trapezoidal unit are connected at the first base and the second base;
• a top cover configured to be connected to the first planar panel and the second planar panel and to cover a top portion of the support structure;
• a first side cover configured to be connected to the first planar panel and the second planar panel and substantially perpendicular to the top cover;
• and
• a second side cover configured to be offset from the first side cover and configured to be connected to the first planar panel and the second planar panel.
