Things to Consider for a Building’s Generator Pad Design


The purchase of a generator comes with necessary decisions that go beyond choosing a model based on needed capacity and size. Indeed, when purchasing a generator, you must also consider the contracting side of things, such as the pad that will support the generator and all its details. Before all the aspects of commercial generator installation are finalized, make sure the mounting pad design specifications are fitted to meet the needs of your generator, and vice versa.

Top Commercial Generator Pad - Details for Attention


Size: How big will the pad’s footprint be?

Though this may sound like an obvious aspect of designing a generator pad, it is vital to make sure the size is appropriately staged for the incoming generator. Fortunately, it’s relatively simple to figure out the size the industrial generator pad should be. Take the size of the generator’s footprint, and add the suitable clearance desired on all sides. The result will give you the appropriate size for the generator pad. Manufacturers tend to advise a minimum of 6-inch clearances, but we recommend a larger space for added safety and access considerations.


Composition: Which concrete mixture is best applied?

Commercial generators are, of course, heavy loads. It is important to make sure the composition of the concrete is fitting to provide the apt support for the incoming generator.


Thickness: How thick should the pad be to properly support the generator?

The required thickness of the generator pad in question is directly related to the weight it intends to support. A structurally-sound pad will see itself weighting as much as or more than the generator meant to stand on top of it. Check the density of the pad against the weight of the generator. If you’re unsure how, connect with APS. We’ll be happy to help.


Conduit Stub-ups: Where will the necessary wires/connections reach up through the pad?

This step can be the most frustrating as it’s so important to get perfect. Conduit locations cannot be changed once the concrete is poured, so first-time correct positioning is vital. In the best-case scenario, the conduit will be brought up directly under the junction box that connect the breakers or the alternator bus to the load leads. It’s often easier to manage for generators that don’t include a subbase tank because the design means less restriction related to where the conduit can be brought up. However, when a subbase tank is included, the alignment must more or less be perfect. Regardless, the incorrect placement of the conduit location usually means a lot of wasted time and money. Your best bet is to consult with a professional before making any definite plans.
