Tucson Electric Power Standards

A contractor’s hub for TEP service, metering, and interconnection — the official documents, the requirements we field most, and an assistant grounded in TEP’s published guidance. TEP’s standards change, so the official documents and TEP are always the final word.

Always Current

Official TEP documents

These link straight to TEP’s own pages and PDFs, so you always get their latest posted version. (TEP doesn’t always announce a new revision — if something looks off, confirm directly with TEP service planning.)

From TEP’s Published Guidance

Requirements we field most

Quick reference based on TEP’s published guidance — confirm the current edition with TEP before you build to it.

Metering

TEP supplies the meter — the meter socket / panel is the customer’s or contractor’s responsibility.
Meter height — center of the meter generally 3′6″ min to 6′3″ max above final grade.
Multiple meters — each panel permanently marked (not painted), typically 1/4″ min letters on a non-ferrous tag riveted to the panel.

Grounding & inspection

Grounding (100–200 A residential, commonly cited) — #6 solid copper GEC; two 8′ × 5/8″ ground rods, first within ~3′ of the panel, second ~6–8′ away. Confirm against the current TEP standard and the NEC.
Inspection commonly checks — meter sockets, connections, trenches, conduit, and address / panel labeling.

TEP approved panels & meter equipment

We’re building a curated, kept-current list of TEP-approved residential and commercial panels and meter sockets — the exact thing that’s hard to find and often out of date elsewhere.

Coming soon. The approved-equipment list is being compiled and verified with TEP and our manufacturer partners so it’s accurate, not guessed. In the meantime, confirm approved panels and meter sockets on TEP’s Electric Service Requirements or directly with TEP — and our team can help you spec a panel that passes the first time. Contact us.

Ask

TEP Standards assistant

Ask about TEP service, metering, grounding, or interconnection. The assistant answers from TEP’s published guidance above and points you to the official document for anything it can’t confirm — it won’t guess approved equipment or revisions.

TEP Assistant

Hi — ask me about Tucson Electric Power service, metering, grounding, or interconnection. I answer from TEP's published guidance and link you to the official document for anything I can't confirm. I won't guess approved panel/meter models or revision numbers — for those I'll point you to TEP.

Try:

How it works & please verify. The assistant is grounded in TEP’s published guidance (linked above), not guesswork — for the approved-equipment list, exact revisions, or commercial tables, it points you to the official TEP document or to confirm with TEP. TEP standards change; the official documents and TEP service planning are always the final word. This is a contractor convenience, not an official TEP publication.
