Besides the unlimited and residential electrical licenses, Florida's Electrical Contractors' Licensing Board (ECLB) certifies several specialty electrical contractors. The ones most people search for are limited energy (often called "low voltage"), sign specialty, lighting maintenance and utility line. Each is a statewide certification with a 100-question technical exam and the shared 50-question Electrical Business exam, both at 75% to pass.
Legal basis
F.S. 489.505(19) defines a specialty contractor as one whose practice is limited to a specific segment of electrical or alarm work "established in a category adopted by board rule." F.S. 489.511(4) makes these optional statewide categories: the existence of a specialty does not itself create a licensing requirement, but it does not remove one that exists elsewhere in Part II. The categories and scopes are in rule 61G6-7.001 (last amended September 25, 2024).
The specialties
| Specialty | Scope in brief (rule 61G6-7.001) |
|---|---|
| Limited energy systems | Wiring, fixtures, apparatus, raceways, conduit and fiber optics not over 98 volts (RMS), excluding work that is part of an alarm system |
| Sign specialty | Structural fabrication (including concrete foundations), erection, installation, repair, service and wiring of electrical and non-electrical signs and outline lighting, up to the last disconnect or terminal points |
| Lighting maintenance | Install, repair, alter or replace lighting fixtures on buildings, signs, billboards, roadways, streets, parking lots and similar structures, not beyond the last supply source, outlet or disconnect |
| Utility line | Transmission and distribution circuits and substation construction for investor-owned utilities, municipal electric utilities and cooperatives under the rural electric authority, between point of origin and point of delivery |
| Two-way radio communications enhancement systems | Systems up to 98 volts (RMS) for two-way radio enhancement in all structures, not including connection to a fire alarm panel |
Details worth knowing
- Limited energy work may also be done by unlimited electrical, Alarm I, Alarm II and residential electrical contractors. It excludes public utility work exempt under F.S. 489.503(4) or under Public Service Commission jurisdiction.
- Sign specialty contractors may provide the metering and main disconnect for remote billboards or signs that stand apart from any building and need no more than 25 kilowatts at 250 volts maximum.
- Two-way radio work may also be done by certified unlimited electrical, certified Alarm I and registered Alarm I contractors. The DBPR candidate booklet we reviewed does not list a separate exam outline for this specialty; ask DBPR how it is tested.
Eligibility
F.S. 489.511(4) says qualification for a specialty created by rule is the same as for other ECLB certification under 489.511(1)(b): age 18, good moral character, passing the exam, and one experience route (for example, 3 years of management experience within the last 6 years, 4 years as a supervisor or contractor within the last 8, or 6 years of comprehensive training, technical education or supervisory experience within the last 12).
Rule 61G6-7.001 states, in its opening paragraph, that to be admitted to a specialty exam a person "must show 6 years of comprehensive training, technical education, or broad experience" in the type of work for which certification is sought. If your experience is close to the line, ask the ECLB which standard it applies to your application.
The exams
| Exam | Scored questions | Time | Passing score |
|---|---|---|---|
| Electrical Business (shared by all ECLB categories) | 50 | 2.5 hours | 75% |
| Specialty Technical/Safety | 100 | 5 hours | 75% |
Both are open book and computer-based at Pearson VUE.

| ADA | 1 to 3 | none | none | none |
Reference list overview
The ECLB uses one reference list for all eight certifications with a column per category. Every category uses NFPA 70 (National Electrical Code), OSHA 29 CFR and the ADA guidelines. Specialty-specific titles on the list include Telecommunication Wiring and the NTC Blue Book Low Voltage Systems (low voltage), Engineering Sign Structures, NEON Techniques and Handling and Design and Control of Concrete Mixtures (signs), and the National Electrical Safety Code and The Lineman's and Cableman's Handbook (utility line). Several editions change on August 21, 2027.
Exam volume
Pearson VUE exam performance reports for 2025:
| Technical exam | Graded attempts | First attempts | First-time pass rate |
|---|---|---|---|
| Limited energy | 156 | 96 | 36% |
| Sign specialty | 39 | 18 | 17% |
| Utility line | 23 | 5 | 0% |
| Lighting maintenance | 7 | 4 | (too few to compare) |
These technical exams have some of the lowest first-time pass rates of any Florida contractor exam. The shared Electrical Business exam had a 63% first-time pass rate in 2025.
Steps
- Pick the specialty that matches your work.
- Document experience (see the eligibility note above).
- Apply to DBPR; once approved, schedule both exams with Pearson VUE.
- Pass each at 75%.
- Complete certification with the ECLB.
FAQ
Is "low voltage license" an official Florida term? The rule calls it the limited energy systems specialty, capped at 98 volts (RMS).
Can a limited energy contractor install burglar or fire alarms? No. The rule excludes work that is part of an alarm system; see the alarm license.
Do these licenses take the CILB Business and Finance exam? No. ECLB candidates take the 50-question Electrical Business exam.
