What this is
Published guides
What each guide answers, and what it rests on
| Guide | The question it answers | The primary source it rests on |
|---|---|---|
| Aluminum wiring | Which of the two products called “aluminum wiring” is in the house | CPSC publications on solid aluminium branch circuits |
| Zinsco panels | How to identify one, and how much of the hazard case is documented | The absence of a CPSC investigation record, stated as such |
| EV charger at home | What the dedicated 240 V circuit, permit and inspection involve | NFPA 70 as the model code |
| Hiring an electrician | What has to be in a quote before you sign it | FTC guidance, CSLB’s contract list and two state statutes |
| Electrical permits | When a permit is required, and where one does not mean an inspection | The model code plus New York City and Texas rules |
| Grounding and bonding | Why the two words are not interchangeable | NFPA 70 as the model code |
| Electrification incentives | Which federal credits still exist | The Internal Revenue Code and the IRS fact sheet |
Every guide carries the document each figure came from and the date we retrieved it.
How these guides are written
Primary sources only. Code statements come from NFPA 70 as the model code. Safety statements come from CPSC. Tax statements come from the statute and IRS guidance, with the page-review date recorded, because a tax page’s review date is part of its evidence. We do not cite a blog that cites a source; we open the source.
Contested evidence is labelled as contested. Several of the best-known claims in residential electrical work rest on field consensus rather than controlled testing. Where that is true, the guide says which is which and lets the reader weigh it, instead of borrowing the confidence of a stronger evidence base.
No do-it-yourself electrical instruction. These guides teach identification, assessment and decision-making, and they name the point where a licensed electrician takes over. Nothing here instructs anyone to work on a live circuit or behind a dead-front cover.
Nothing rests on our contractor store. That store covers five states and 74% of it is Florida. It has no bearing on federal law, the model code or the national housing stock, and it is not used to support a national claim anywhere in this section.

Primary-source research and fact checking
We read the model code, the federal safety notice, the municipal fee sheet or the utility tariff ourselves, and we publish the figure with the document it came from and the date we retrieved it. Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. HyreElectrical does not perform, supervise or warrant electrical work. Authorship is organisational: this desk, not a named persona.

How this desk works
- Primary sources only. Code statements come from NFPA 70 as the model code. Safety statements come from CPSC. Permit fees come from the city or county fee sheet. Utility charges come from the filed tariff. We do not cite a blog that cites a source; we open the source.
- Our contractor store is five states, and 74% of it is Florida. Any figure built on that store is titled to those states and names the concentration in the first screen. It is not a national sample of electricians.
- Load calculations on this site are a published simplification in the shape of NEC 220.82 — first 10 kVA at 100%, remainder at 40%, HVAC at 100%, EVSE at 125%. They are labelled as not a stamped calculation. A licensed electrician using the adopted edition does that work.
- No national price for a panel upgrade is shipped. Labour rates, the adopted code edition, whether the utility is involved, and the state of the existing wiring move the invoice too far for a roundup to help. Cost intent lives on the cost page; this page explains the decision.
- We do not perform electrical work, and we take no payment for placement, ranking or a favourable mention. Nobody buys a position on this site.
