Editorial policy
How the writing on this site is produced, checked and corrected — including the part most publishers leave out.
What we publish, and why
Every article answers one question an installer, electrician or homeowner actually searches for, and answers it with a worked calculation rather than a summary. Where a number appears, the code section it derives from is named — 690.7, 690.8, 705.12(B)(3), 310.15(B)(1), 220.82 — so a reader can check it against their own copy of the code.
How the calculations are produced
This is the part worth stating plainly. The arithmetic in these articles is generated by the same deterministic engine that sizes conductors and overcurrent devices in the product itself, using the same equipment specifications the software recognises. It is not typed by hand into prose, and it is not estimated.
The reason is accuracy, not convenience: a hand-written article drifts from the software the first time a correction factor changes, and then the site and the product disagree. Generating both from one engine means an article cannot quietly become wrong while the product stays right.
The narrative around each calculation — what the number means, when the rule bites, what installers get wrong — is written and edited by us.
Review
Articles that state a code requirement are checked against the published text of the National Electrical Code edition named in the article. Where jurisdictions commonly amend a rule, the article says so rather than presenting one answer as universal.
What we will not do
- We do not publish content written to fill a keyword with no question behind it.
- We do not present a calculation without its inputs and its code basis.
- We do not claim an article replaces a licensed electrician or engineer. It does not.
- We do not accept payment to feature a manufacturer, and no article is sponsored.
Corrections
If we get something wrong, we correct the article and note the date. Report an error to support@onelinestudio.us with the subject line “Correction”, naming the page and the code section you are reading it against. We aim to respond within two business days.
Advertising and independence
Public pages may carry advertising served by Google, described in our privacy policy. Advertisers have no influence over what we publish, and no article is written or altered to suit one. Where we name equipment it is because the calculation needed a real specification, not because a manufacturer asked.
Who writes it
OneLine Studio is built and written by the same small team at Zappfin LLC. There is no outsourced content desk. Questions about a specific article go to support@onelinestudio.us.
