Short answer: no permit to diagnose; panel work is permitted. Reading the trip code and unplugging loads is diagnosis. The full answer and its source are below, with the code requirements and mistakes that trip up Orlando homeowners.

The permit answer

No permit to diagnose; panel work is permitted. Reading the trip code and unplugging loads is diagnosis. Anything inside the panel is electrical work — Orange County requires an electrical permit for panel changes and service upgrades, and even a like-for-like breaker swap is a gray area worth the county's call.

Key facts before you start

A breaker that keeps tripping is doing its job: it protects the wire in the wall, not the appliance, so a bigger breaker is never the fix. This is the mistake that burns houses down, and the code puts hard numbers on it. NEC 240.4(D) caps overcurrent protection on small copper conductors at 15 A for 14 AWG, 20 A for 12 AWG and 30 A for 10 AWG. Put a 20 A breaker on a 15 A circuit's 14 AWG wire and you have not solved anything — you have raised the trip point above what the wire can carry, so the next overload heats the cable inside the wall instead of throwing the handle. Florida note: the FBC-Residential does not carry its own electrical text, so the NEC section is the Florida rule, not a national aside.
Before you guess, read the code the breaker already stored — a modern AFCI or dual-function breaker RECORDS why it tripped. Square D QO/QOB combination AF: on power-up the LED reports the previous electronic trip — solid for 10 seconds = arc fault, 2 pulses = ground fault, 7 pulses = "Arc Fault protection unresponsive," and an LED that never lights = "No fault stored, thermal overload, short circuit." Replay it WITHOUT tripping the breaker: leave the handle ON and quickly press and release TEST. Eaton's Type CH AF/GF instead blinks one of six numbered codes with "lifetime trip code retention." Two traps: Schneider's stored result self-clears once the breaker has been "powered continuously for 27 days," so a blank log on a long-quiet circuit proves nothing; and a dark LED is not innocence, it means the mechanical half acted — overload or short.
The two arc codes split the job between you and an electrician, and they mean opposite things. SERIES arc: "A low current arc has been detected within one of the current pathways... typically found in worn or degraded appliances and extension cords, poor connections in appliances or fixtures." Eaton's resolution is to "identify the equipment causing the tripping, and repair or replace" — that is unplug-things-one-at-a-time territory, and it is often a lamp cord or a space heater. PARALLEL arc: "A high current arc has been detected between two conductors... usually found in installed wiring where the wire has been compromised by a nail or screw, tight staple, and damaged insulation," resolution "locate fault location and replace wire." That is inside the walls. Stop and call an electrician.
Square D can also be asked, on demand, to NAME the fault — Time Saver Diagnostics. Put the breaker OFF, firmly press and HOLD the white TEST button, move the handle to ON, and time the trip: under 1 second = "Fault to Ground"; 2.0 seconds = "Arc Fault"; 5.0 seconds = "Procedure Complete," which expressly "Includes: no fault, thermal overload, short circuit"; 10.0 seconds = out of memory. So 5.0 s is NOT the all-clear — it rules out arc and ground faults and leaves overload or short, which you separate by behaviour: an overload takes a little while and returns whenever you re-run the same load, a dead short trips instantly and every time regardless of what is plugged in. For an overload, move a load to another circuit before assuming anything is broken. Clear a stored result by running the procedure 6 times until it reads 5.0 s.
Three AFCI facts explain most "nuisance" trips that no appliance hunt will ever find. SHARED NEUTRAL: Schneider states the arc-fault detection device "is not designed or intended for use on circuits in which the neutral conductor is shared with other circuits. The circuit breaker will nuisance trip in 'shared neutral' circuits" — so an AFCI retrofitted onto an older multi-wire branch circuit is tripping on wiring topology, not on a fault, and the fix is separating those neutrals, not swapping appliances. WRONG VARIANT: a "QO plug-on neutral arc fault circuit breaker may only be used in plug-on neutral load centers." NOT A GFCI: the combination AF breaker "does not meet the requirements for Class A ground-fault circuit protection," so it never substitutes for GFCI protection the code requires.
If the breaker will not stay on — or will not trip when tested — suspect the breaker before the circuit. Schneider requires testing an AF breaker after installation and "monthly thereafter": loads off, power on, handle ON, press TEST. If it does not trip, an electrician removes the load wires and repeats; still no trip means "replace the circuit breaker," while a breaker that DOES trip once the wires are off means the branch circuit is at fault and the breaker stays. Eaton's unit likewise runs a "continuous self-test" and "will not allow the AF/GF breaker to re-latch if it detects a malfunction in the AF/GF detection circuit" — resolution "replace the breaker," so an AFCI that refuses to latch on a circuit that was fine yesterday is plausibly a dead breaker. Never megger or hi-pot test one: Schneider warns those "will damage circuit breaker."
Know the three stop-now signs and the one panel question. Stop if the breaker is warm to the touch, if there is any burning or hot-plastic smell, or if there is scorching or discoloration at the panel — none of those are reset-and-see conditions. Stop too on an Eaton OVERVOLTAGE code: "the breaker will trip if it experiences voltage of 160 V rms or greater," resolution "investigate utility power for imbalance in the phases or loss of neutral" — a lost service neutral is utility-side, dims one room while brightening another, and is a call-now condition. The panel question: if the label says Federal Pacific (Stab-Lok) or Zinsco, the breakers themselves are the suspect part and many Florida insurers require replacement — see the flickering-lights guide. And note who may legally do the work: electrical is never covered by Florida's handyman exemption, so hiring means a licensed electrical contractor, or an owner-builder permit if you are doing it yourself on your own home.

What it costs

DIY: $5–$30 for a standard 1-pole breaker (15–40 amp) as a part — but see the panel-work permit rule above before touching anything inside the panel
Hiring it out: $100–$260 to have an electrician replace a breaker switch (standard 1-pole $100–$180); a full panel replacement runs $850–$4,000
Diagnosing WHY it trips can take longer than the swap — and a breaker that keeps tripping can indicate a dangerous fault.
