HyreElectrical guides

What the thing is, how to tell what you have, and where the evidence actually stands — including where it is contested.

What this is

Explanatory pages on residential electrical systems, written from primary sources: NFPA 70 as the model code, Consumer Product Safety Commission publications and investigation records, the Internal Revenue Code and IRS guidance, and Census housing tables. Where the evidence for a common claim is contested or thin, these guides say so rather than repeating the confident version. Every figure carries the document it came from and the date we retrieved it. Authorship is organisational — the HyreElectrical Research Desk, never a named persona. HyreElectrical does not perform, supervise or warrant electrical work, and takes no payment for placement, ranking or favourable mention.

What each guide answers, and what it rests on

GuideThe question it answersThe primary source it rests on
Aluminum wiringWhich of the two products called “aluminum wiring” is in the houseCPSC publications on solid aluminium branch circuits
Zinsco panelsHow to identify one, and how much of the hazard case is documentedThe absence of a CPSC investigation record, stated as such
EV charger at homeWhat the dedicated 240 V circuit, permit and inspection involveNFPA 70 as the model code
Hiring an electricianWhat has to be in a quote before you sign itFTC guidance, CSLB’s contract list and two state statutes
Electrical permitsWhen a permit is required, and where one does not mean an inspectionThe model code plus New York City and Texas rules
Grounding and bondingWhy the two words are not interchangeableNFPA 70 as the model code
Electrification incentivesWhich federal credits still existThe 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 We do not cite a blog that cites a source; we open the source.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.

Questions

Do these guides tell me how to do electrical work myself?
No. The guides teach identification, assessment and decision-making, and they name the point where a licensed electrician takes over. Nothing in this section instructs anyone to work on a live circuit or behind a dead-front cover.
Who writes the HyreElectrical guides?
Authorship is organisational: the HyreElectrical Research Desk, never a named persona. HyreElectrical does not perform, supervise or warrant electrical work, and takes no payment for placement, ranking or favourable mention.
Where do the figures in these guides come from?
Primary sources only. Code statements come from NFPA 70 as the model code, safety statements from the Consumer Product Safety Commission, tax statements from the statute and IRS guidance, and housing figures from Census tables. Every figure carries the document it came from and the date we retrieved it.
Does HyreElectrical’s contractor database inform these guides?
No. 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.

Data as of Sources retrieved September 2026. Authorship on this site is organisational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
