Summer Electrical Safety Tips for Chicago Homes | E&P Electric

Central air conditioning draws significant power:

• Typical 3-ton AC unit: 15–20 amps at 240V
• Requires dedicated circuit: No other appliances should share this breaker
• Full home load: When AC runs with heat, water heater, and other appliances, demand is extreme

Signs your AC circuit is overloaded:

• Breaker trips when AC runs (especially if other appliances are on)
• AC struggles to cool when other devices are running
• Burning smell near AC unit or breaker
• AC outdoor unit making humming/buzzing sounds

Before turning on AC for the season:

Electrical connections:

• ✓ Outdoor unit has proper disconnect switch (safety requirement)
• ✓ All connections are tight (loose connections overheat)
• ✓ No corrosion on terminals (salt air exposure in Chicagoland)
• ✓ Circuit breaker is labeled and easily accessible
• ✓ Wire gauge is appropriate for load (typically 10 or 8 AWG)

Thermostat & controls:

• ✓ Thermostat batteries are fresh
• ✓ No error codes displayed
• ✓ AC responds to temperature adjustment

If AC won't start or breaker keeps tripping:

• Call E&P Electric before summer peak (avoid long wait times)
• Don't keep resetting breaker (fire hazard)
• Circuit may need upgrading (dedicated 20A or 25A service)

Manage summer electrical demand:

• Don't run multiple high-draw appliances simultaneously (AC + electric water heater + range)
• Schedule heavy usage during cooler morning/evening
• Use ceiling fans to reduce AC load (circulating cool air is efficient)
• Keep AC filters clean (dirty filters reduce efficiency, increase demand)
• Ensure outdoor AC unit has shade and airflow (efficiency improves in less extreme heat)

Professional AC service (separate from electrical, but related):

• Typically recommended annually (spring or early summer)
• Includes refrigerant check, electrical connection verification
• Address any electrical issues before summer peak

Ground fault circuit interrupters are essential outdoors:

• Protect against shock from water exposure
• Should be on every outdoor outlet
• Should also protect outdoor equipment (pool pump, sprinkler timer, etc.)

Test outdoor GFCI outlets:

• Press TEST button (outlet should lose power immediately)
• Press RESET to restore power
• If test button doesn't work, GFCI may be bad (replace or have E&P Electric verify)

Outdoor outlet safety checklist:

• ✓ GFCI protected (test monthly)
• ✓ Weatherproof cover in place
• ✓ No standing water or debris
• ✓ Extension cord is heavy-duty, outdoor-rated
• ✓ Cord is properly grounded (three prongs)

Proper extension cord use prevents shocks and fires:

Cord selection:

• ✓ Outdoor-rated cord (marked "W" or "W-A")
• ✓ Properly grounded (three-prong, not two-prong)
• ✓ Appropriate gauge for distance (distance + amperage determines gauge):
• Up to 50 feet: 12 AWG minimum
• 50–100 feet: 10 AWG minimum
• 100+ feet: 8 AWG (thick cord)
• ✓ Heavy-duty (13 amps or higher rating)

Extension cord safety rules:

• ✓ Inspect for cuts, cracks, or damage before using
• ✓ Keep away from water (lay on dry ground, not in wet grass)
• ✓ Don't use extension cord in wet areas without GFCI protection
• ✓ Unplug when not in use
• ✓ Don't run cord under carpets or through water
• ✓ Keep cord away from heating elements (stove, grill)

Never daisy-chain extension cords (cord to cord to cord). This creates voltage drop and overheating risk.

Using outdoor equipment electrically:

• Lawnmower: GFCI protection, inspect cord before each use
• Weed trimmer: Battery-powered preferred (lower shock risk)
• Power tools: GFCI protection, proper grounding
• Outdoor lights: GFCI protected (outdoor-rated fixtures)
• Pool/spa equipment: Dedicated circuits, proper bonding (see pool section below)

Pools and hot tubs require significant electrical work:

Dedicated circuits:

• Pool pump: 240V dedicated 30–50A circuit
• Pool heater: 240V dedicated circuit (30–60A depending on size)
• Jet tub/hot tub: 240V dedicated 30–50A circuit

All circuits must have:

• Proper breaker size for pump/heater load
• Ground fault protection (GFCI)
• Bonding and grounding (critical for shock prevention)
• Disconnect switch within 5 feet of pool (electrical code requirement)

Bonding connects all conductive surfaces to prevent shock:

• Pool walls, pump, lights, ladders, diving board all bonded together
• Grounding connects bonded system to earth (safety outlet)
• Without proper bonding, touch a pool edge while stepping in water = electrocution risk

Professional installation required: Pool bonding is complex and must meet code. DIY work is dangerous and illegal in Chicago.

During swimming:

• No electrical outlets or equipment within 6 feet of pool edge
• No overhead power lines directly over pool (call ComEd if any present)
• Underwater lights require special fixtures (not standard outlets)
• Never use standard electrical extension cords near pool

Equipment operation:

• Turn off pump and heater during thunderstorms (lightning risk)
• Ensure disconnect switch is working
• Don't touch pool pump while barefoot on wet ground (electrical path risk)
• Metal ladders may need bonding (consult E&P Electric)

Portable hot tub safety:

• Requires dedicated 240V 30–50A circuit (not extension cord)
• Must have proper disconnect switch
• Bonding and grounding essential (even for portable tubs)
• GFCI protection mandatory
• Professional installation required (not DIY)

Pool electrical installations must be professional:

• Licensed electrician required (legal in Illinois)
• Knowledge of pool code (different from standard residential)
• Proper bonding expertise
• Insurance covering pool work
• Code inspection and certification

E&P Electric has pool electrical experience and ensures code-safe installations.

Chicago summers bring thunderstorms with lightning risk. Lightning strikes can:

• Kill or injure occupants (if inside at outlets/appliances, or outside touching conductive surfaces)
• Damage electrical equipment (TV, computer, appliance failure)
• Cause fires (ignite wiring insulation, roofing materials)
• Surge through power lines (damage utilities, neighbors)

Electrical safety:

• Avoid touching light switches, outlets, appliances, plugged-in devices
• Unplug high-value electronics before storm (TV, computer, appliances)
• Stay away from water (tub, sink, outdoor faucet)
• Avoid using corded telephone
• Don't use pool/hot tub

Stay indoors in core of home (away from windows, doors, plumbing).

Whole-home surge protection:

• Surge protector at main panel ($200–$500 installation)
• Protects all circuits from lightning-induced surges
• Recommended for all Chicago homes
• Prevents cascading equipment failures

Power strips & individual surge protection:

• Help, but less reliable than whole-home suppression
• Still leave some equipment vulnerable
• Better than no protection

Uninterruptible power supplies (UPS):

• Battery backup for computer, critical equipment
• Allows safe shutdown during power loss
• Also provides surge protection

Electrical system hazard:

• Call E&P Electric immediately (may have hidden damage)
• Don't assume no damage (wiring can be damaged internally)
• Have electrician inspect before resuming normal use
• May require whole-home surge protector upgrade

Heat stress on electrical systems:

• High temperatures reduce wire efficiency, increase fire risk
• Ensure attic ventilation (heat buildup damages insulation)
• Keep panel area cool (avoid stacking items around outdoor panel)
• Air condition critical during extreme heat (draws heavy current)

Outdoor outlet maintenance:

• Monthly GFCI test (especially in wet/humid areas)
• Clear debris, trim vegetation
• Inspect weatherproof covers

Backup power planning:

• If you lose power in summer, AC won't run (dangerous heat)
• Consider generator for high-risk homes (elderly, medical conditions, etc.)
• At minimum, have portable AC unit or window AC with battery backup

Call E&P Electric if you notice:

• Breaker frequently trips (AC, multiple appliances)
• Outlets feel warm or smell burnt
• Flickering lights when AC runs
• Buzzing or humming from outdoor AC unit
• GFCI outlets not resetting
• Any electrical smell or visible damage
• Recent lightning strike nearby
