1.2 Current SPS 316 Adoption, Enforcement & Wisconsin Amendments
Key Takeaways
- Wisconsin SPS 316 now adopts the 2023 NEC for state electrical-code administration, but DSPS continues to test from the 2017 NEC through September 30, 2026 and changes the exam reference to the 2023 NEC on October 1, 2026.
- SPS 316 can substitute text, omit a national NEC requirement, or add a Wisconsin rule; the state amendment controls whenever it changes the adopted NEC.
- The 2026 rule adds permit rules for covered work on vacant land or structures and requires municipal electrical-inspection records to be retained for 7 years after completion.
- High-yield current amendments include Wisconsin-specific GFCI/AFCI and island-receptacle rules, an 8-foot inside limit for certain feeder/service conductors, outside-disconnect location limits, mandatory supplementation of a single rod/pipe/plate electrode, and omission of NEC 225.41 and 230.85.
- DSPS does not publish percentage weights for the journeyman exam; the official scope is the authorized SPS 305, SPS 316, and NEC reference set.
1.2 Current SPS 316 Adoption, Enforcement & Wisconsin Amendments
The National Electrical Code becomes enforceable in Wisconsin only through state adoption. SPS 316 incorporates an NEC edition and then changes selected provisions. A Wisconsin answer therefore has two layers: first find the national rule, then determine whether SPS 316 substitutes, excludes, or supplements it.
Code edition versus exam edition
Wisconsin's 2026 SPS 316 rule adopts the 2023 NEC for state code administration. The examination calendar has a short transition lag: the DSPS Journeyman Electrician exam page authorizes the 2017 NEC through September 30, 2026 and the 2023 NEC beginning October 1, 2026.
This distinction is essential:
- On a job, determine which code applies to the installation, permit, and jurisdiction.
- On the exam, use the code edition and SPS material on the DSPS reference list for the scheduled date.
- Do not answer a pre-October exam question from an unapproved 2023 book, and do not prepare for an October-or-later exam as though Wisconsin still tests only the 2017 edition.
How an amendment operates
SPS 316 uses three common mechanisms:
- Substitution: Wisconsin replaces national wording. Apply the state text, not both rules at once.
- Exclusion: Wisconsin says a cited NEC requirement is not included. Do not enforce that omitted national provision as part of SPS 316.
- Addition: Wisconsin adds a state requirement alongside the adopted NEC.
Exam stems often turn on the mechanism. Highlight words such as “substitute,” “not included,” and “in addition to” in the bound SPS 316 reference.
Administration, permits, and records
The Authority Having Jurisdiction may be DSPS or a municipality exercising the applicable inspection authority. Verify the permit and inspection office for the actual location; do not assume every project is handled by the same state office.
The current rule addresses electrical work on vacant land and on or within structures and adds targeted permit rules. It also requires municipal electrical-inspection records to be retained for 7 years after completion; state-contracted inspectors follow the record provisions in the contract that applied when the inspection was completed.
SPS 316 also defines the AHJ for its administration and retains the variance process. A variance or special permission is formal approval, not a field electrician's personal judgment that an alternative is “equivalent.” Listed or labeled equipment is installed and used according to its instructions unless those instructions conflict with the Wisconsin code.
High-yield 2026 amendment map
Use this map as an index, then read the actual section:
| Wisconsin section | Exam-facing effect |
|---|---|
| SPS 316.210 | Substitutes the dwelling GFCI scope, omits selected 2023 GFCI/AFCI provisions, and replaces the island/peninsula receptacle rule. |
| SPS 316.220 | Defines dwelling floor area for load calculations and excludes open porches, garages, and unfinished areas not adaptable to future habitable or occupiable use. |
| SPS 316.225 | Limits certain feeder/branch-circuit wiring to 8 feet inside before the disconnect; an outside disconnect must be within sight and no more than 30 feet from the served structure; NEC 225.41 is omitted. |
| SPS 316.230 | Applies the corresponding 8-foot service-conductor rule and outside-disconnect location; NEC 230.85 is omitted. |
| SPS 316.250 | Requires a single rod, pipe, or plate electrode to be augmented and contains Wisconsin grounding/bonding amendments. |
Other amendments remain important. Use the table of contents and index in the current SPS 316 rather than assuming this high-yield list is exhaustive.
Avoid obsolete Wisconsin rules
The 2026 final order repealed several prior provisions, including older text in SPS 316.230 and the former state sections across parts of Articles 511 through 701. That means a familiar rule from an old Wisconsin handout may no longer exist as a state amendment. For example, current SPS 316 omits the national dwelling emergency-disconnect mandate in NEC 230.85; an old “Wisconsin cold-sequence” study note is not a substitute for current section text.
Blueprint and study method
DSPS publishes authorized references and logistics, but it does not publish a percentage-weighted journeyman content outline. Treat any neat five-domain percentage chart as a study organizer, not an official weighting.
For each practice problem, write three labels: NEC edition, NEC section, and SPS effect. If the state section says “not included,” stop applying that national paragraph. If it substitutes wording, solve from the substituted text. This habit is more reliable than memorizing an unsourced list of “Wisconsin exceptions.”
Which NEC edition does DSPS authorize for a Wisconsin Journeyman Electrician exam scheduled on October 5, 2026?
If SPS 316 states that a specific NEC requirement is “not included as part of this chapter,” how should it be treated for Wisconsin code enforcement?
How long must municipal electrical-inspection records be maintained under the current SPS 316 rule?
Does DSPS publish official percentage weights for the Journeyman Electrician exam domains?
