GFCI, AFCI, Tamper-Resistant and Weather-Resistant: What Is the Difference?

These four labels address different hazards. Learn how shock protection, arc-fault protection, internal shutters and outdoor ratings work together—and what to ask before replacing an outlet.

Four complementary protection features: benefits, applications and limitations.

FeatureBenefitWhere it appliesLimitation or tradeoff
GFCIDetects current imbalance and interrupts power to reduce severe shock risk.Especially relevant where electrical equipment may encounter water.Does not supply tamper-resistant shutters or a weather rating.
AFCIDetects hazardous arcing associated with electrical fires.Relevant to dwelling circuits covered by applicable AFCI requirements.AFCI alone is not equivalent to GFCI shock protection.
Tamper-resistant, or TRBuilt-in shutters restrict insertion of most foreign objects.Relevant to household receptacles, including locations accessible to children.Does not detect ground faults or hazardous arcing.
Weather-resistant, or WRUses construction designed to resist outdoor environmental exposure.Relevant to receptacles in wet or damp outdoor locations.Still needs suitable enclosure protection and applicable GFCI protection.

Portable or Standby Generator? Compare the Practical Tradeoffs

The right generator is the one that fits your essential loads, property and ability to operate it safely. Compare three arrangements, from appliance-only portable backup to automatic standby.

Three backup-power arrangements and where their limitations matter

OptionBenefits and applicabilityTradeoffs and limitationsMain cost considerations
Portable generator with suitable appliance cordsUseful for a limited group of compatible plug-in essentials; generally lower initial expense.Manual placement, starting and refueling; cord ratings and appliance demand limit use. Does not supply hardwired circuits this way.Generator, suitable cords, safe fuel storage and ongoing upkeep.
Portable generator with manual transfer equipmentCan supply selected household circuits, including suitable hardwired loads, when professionally designed.Still requires manual generator operation; transfer equipment does not increase generator capacity.Generator plus compatible transfer equipment, inlet, electrical work and applicable permits.
Permanent automatic standby generatorAutomatic outage response; can serve selected circuits or broader household needs when appropriately sized.Requires a feasible permanent site, fuel supply and professional installation; automatic operation is not maintenance-free.Generator, automatic transfer switch, site preparation, fuel work, permits and maintenance.

Whole-House Surge Protection, Plug-In Protectors and UPS Units Compared

Surge protection limits brief voltage spikes. A UPS supplies temporary battery power. Compare where each option acts, what it cannot do and when a combination makes sense.

Power strips, surge protectors and UPS units: practical differences

OptionWhere it actsBenefits and best fitTradeoffs and limitations
Ordinary power stripAt an existing receptacleAdds connection points for suitable loads within its rating.No surge suppression unless specifically included; no battery backup; does not increase circuit capacity.
Panel-level surge protective deviceAt the electrical service or distribution panel, as permitted by its listingProvides a broader layer of surge protection for connected electrical systems.Requires appropriate installation; supplies no outage power and is not an unlimited shield.
Plug-in surge protectorAt selected cord-connected equipmentAdds point-of-use surge protection for equipment plugged into it.Does not protect unrelated circuits or supply battery power; load and installation limits apply.
UPS battery-backup unitAt selected electronicsProvides temporary battery power; surge protection and voltage-regulation features depend on the model.Capacity and runtime are separate limits; some outlets may be surge-only rather than battery-backed.

Questions covered in these guides

  • Can one receptacle be GFCI, tamper-resistant and weather-resistant?
  • Does every protected outlet need TEST and RESET buttons?
  • Does GFCI protection add a ground wire to an older outlet?
  • Will AFCI protection fix damaged wiring?
  • Is a self-testing GFCI maintenance-free?
  • Does electric start make a portable generator automatic?

Check the details that apply to your needs. Each linked guide identifies its sources and the conditions that may affect the comparison.
