What's the Difference Between Commercial and Residential Blueprints?

When an electrician gets a job that needs to be built, how does that electrician know exactly WHAT they are building? Well, it usually because there are a set of drawings that shows them what to build! But what about residential vs commercial- is there a difference in those drawings? In todays episode of Electrician U, Dustin talks about the construction drawings and the nuances between Commercial and Residential. 🤘⚡️EU Learning System⚡️🤘 For Individuals --- https://electricianu.com/learning-sys...

Generally, these drawings are drawn by an Architect and are meant to convey what the overall house will look like. There will be multiple sheets but, more than likely, the sheets will all start with the letter A (standing for architectural). The bulk of the drawings for a residential project will be centered around what the house will LOOK LIKE. There will more than likely be an electrical sheet(s), but these electrical sheets are general in nature only. As the architect has had much training in designing the LOOKS, they don’t know all the ins and outs of the NEC. But the electrician does! So, while the electrical sheets for a residential project show generalities and maybe a few specific OWNER requirements, it is up to the installing electrician (and the company that they work for) to design the overall electrical system for the residence. Commercial sets of drawings are much different and can vary in size from a dozen sheets on a smaller job to several hundred sheets (and more) on larger projects. The biggest difference between residential and commercial drawings is that the commercial drawings are drawn by ENGINEERS in lieu of an ARCHITECT. So the entire MEP (Mechanical, Electrical, Plumbing) set will have Engineers stamps if you look at the sheet. In the electrical sheets, everything is laid out exactly where the engineer believes it should be placed and what exactly the installing electrician is placing there. Not saying that we wont move things (even engineers are not perfect and cannot foresee every issue before we get there!!) if required, just that the intent is spelled out in much more detail for us. A commercial set of drawings will also have all of the different facets of an electrical job spelled out in much greater detail. So, you will have lighting drawings, power drawings, a single line drawing (one that shows ALL the gear/panels/transformers/etc. with conduit and wire sizes- electrician just needs to adjust for errors, voltage drop, or changes), grounding, data, security, fire alarm, and other systems. Device placement on a commercial project shall be as shown on the drawings whereas on a residential project the installing electrician shall install per the NEC while keeping the architects design intent in mind. There is a long ongoing battle vs electricians as to whom is actually better- residential or commercial. Commercial electricians think they are better than residential electricians as the projects are much larger, the materials are tougher and more diverse, and the projects are seen on a grander scale. Residential electricians believe that they are better than commercial electricians since everything is spelled out for the commercial electricians and that residential is left to figure things out on their own.
