(a)Before any electrical wires or electrical apparatus shall be installed for lighting or power purposes, including fire alarm, area of refuge, and other such emergency and life safety systems, or any electrical construction work done, except minor electrical work, an electrical permit shall be obtained from the Electrical Inspector by a State of Wisconsin licensed Electrical Contractor as defined in SPS 305. ...

Full Breakdown
Before any wiring or apparatus for lighting, power, fire alarm, area-of-refuge or other emergency systems is installed, § 10-90(a) requires an electrical permit obtained by a State of Wisconsin licensed Electrical Contractor, who must be or employ a Licensed Master Electrician or Residential Master Electrician under SPS 305. A permit is also required for outlet installation and low-voltage wiring (50 volts and below) under § 10-90(b), and for demolition or removal of panelboards, transformers and similar equipment under § 10-90(c). Emergency work may start before a permit issues if the Electrical Inspector is notified the same day, or the next business day if the Building Division is closed, per § 10-90(d).
Permits expire 12 months after issuance and require a new permit at the regular fee if they lapse, § 10-90(e). Contractors must annually file license copies, addresses and phone numbers for both the licensed contractor and the master electrician under § 10-91(a), and homeowners may only self-install branch circuit wiring in their own single-family residence, § 10-91(d). Section 10-92(a) adopts the current National Electrical Code and Wis. Admin. Code SPS 316 and 305 by reference. The Electrical Inspector can disconnect service immediately in an emergency or safety-risk situation under § 10-89(g)(2), and after-hours inspections carry a special fee under § 10-89(h).
Variances to the NEC go to the State; variances to the local article go to the City of Janesville Zoning Board of Appeals under § 10-96.
Violations & Fines
Under § 10-97, anyone who violates the Electrical Code or an order issued under it faces a fine of not less than $25.00 nor more than $500.00 plus prosecution costs upon conviction. Nonpayment can mean commitment to the Rock County Jail for not less than five nor more than 60 days. Each day a violation continues is a separate offense, and beyond the fine the City may pursue injunction, mandamus or abatement action, and the City Council may revoke any related license or permit.
