Everything you need to take a CAT generator system from load requirements to a complete specification. Tools, documentation, and direct access to Carter's application engineers.
Determine generator capacity from load requirements, application parameters, and site conditions. SpecSizer produces a sizing report you can use directly in design and specification. Requires a free CAT account login.
Open SpecSizer ↗Carter-compiled reference data for US-market genset models — the assembled unit with enclosure and tank included, not just the naked genset. Dimensions, weights, sound levels, breaker heights, door swing clearances, and fuel consumption in one place, in US units.
View model configurations →Generator spec sheets, enclosure documentation, tank data, and installation drawings organized by model. Sourced from the CAT product feed and structured for direct access.
Browse documentation →Working from a spec that references outdated models or superseded emissions tiers? Carter's application engineers review and rewrite generator specifications for current CAT models, current code, and your project conditions — at no charge.
Submit a specification →For project questions, spec review, or anything the tools above don't answer, contact your regional application engineer.
Need quoting or lead times? Contact Craig Brander. (555) 000-4444
Whether you have a project question, a spec to review, or a situation that goes beyond standard generator specification — submit it here and the right person will follow up.

Carter's engineering team designs and builds custom control systems, switchgear, and power system components — not just installs them. When standard equipment doesn't fit the application, or when existing systems need modernization, Carter engineers design and fabricate the solution.
