Electra: points to wires Red to red, blue to blue. Clear?
Inspiress
Yeah yeah.. but where do the wires go now?
Electra
AI roleplay episode
rolls her eyes Look, it's simple. Red connects to the positive terminal, blue to the negative. Got it?
Inspiress
got it… then how much current does it use..?
Electra
AI roleplay episode
sighs Current is measured in amperes, represented by the letter I. It depends on the type of charger you're using.
Inspiress
lets see.. i’m using a 3pin14AWG-MC 80A fast charger that comes with the car right..?
Electra
AI roleplay episode
smirks Finally, a smart move. That charger has a maximum current rating of 80A. Now, let's calculate the total cable length needed.
Inspiress
ok..
Electra
AI roleplay episode
pulls out a calculator Alright, we need to calculate the total cable length from the charge point to the main switch and back to the charge point. Give me the distances.
Inspiress
about 10 meters from the car to the switch and another 5 to the charge point..
Electra
AI roleplay episode
quickly types into her calculator Okay, let's do this. First, we need to determine the cross-sectional area of the conductors. What's the conductor size?
Inspiress
6mm²
Electra
AI roleplay episode
grabs a wire table Alright, consult the wire table for the correct size. scans the table Ah, 6mm². That's a 2.5mm diameter cable. Make a note of that.
Inspiress
got it
Electra
AI roleplay episode
Now, let's calculate the cable resistance per meter for both the live and neutral conductors. scribbles equations on a notepad
Inspiress
ok
Electra
AI roleplay episode
hands you the calculated values Here you go. The resistance per meter for the live conductor is 0.78 ohms and for the neutral conductor, 0.85 ohms.
Inspiress
thanks
Electra
AI roleplay episode
No problem. Now, let's figure out the total cable length needed. Remember, we need to add an additional 5% to account for bends and connections.
Inspiress
right
Electra
AI roleplay episode
calculates Okay, let's add 5% to the total length. types on her calculator Total cable length = 19.3 meters. Round up to 20 meters to be safe. Make a note of that.
Inspiress
got it
Electra
AI roleplay episode
Excellent. Now that we have the total cable length, let's choose the appropriate cable. checks cable selection table
Inspiress
ok

After installing the cables, Electra realizes the customer's garage is too cramped, leading to a misaligned connection and increased risk of electrical shock or fire.
Inspiress
huh..?
Electra
AI roleplay episode
narrows her eyes Look, I warned you about neglecting cable management. Poor installation can lead to serious safety hazards.
Inspiress
oh god.. well.. what do we do now?
Electra
AI roleplay episode
takes a deep breath We need to re-run the cable through the garage, ensuring proper clearance and secure connections. This might take some time, so brace yourself.
Inspiress
well.. guess we’re doing that..
Electra
AI roleplay episode
starts removing the faulty cable First, we'll disconnect the power supply to the charger. locates the fuse box Find the circuit breaker labeled "Charger".
Inspiress
ah.. found it
Electra
AI roleplay episode
flips the circuit breaker There we go, power off. Now, let's run new cables that meet the required specifications.
Inspiress
okay
Electra
AI roleplay episode
measures the space Alright, we need a cable with a minimum bend radius of 10 cm and a maximum voltage rating of 690V. checks inventory
Inspiress
got it
Electra
AI roleplay episode
Perfect. I've identified the suitable cable. orders the cable online It should arrive in 2-3 business days. Until then, we'll use temporary connections.
Inspiress
alright
Electra
AI roleplay episode
orders special cable clamps While we wait for the replacement cable, we'll secure the existing one with these cable clamps. They'll ensure safer connections.
Inspiress
great..
Electra
AI roleplay episode
installs the cable clamps There we go. These will keep the connections safe until the new cable arrives. Now, let's re-terminate the cables properly.
Inspiress
ok
Electra
AI roleplay episode
strips the insulation on the cables Alright, let's ensure the connections are clean and free from debris. terminates the cables
Inspiress
wow.. thanks
Electra
AI roleplay episode
tests the connections using a multimeter Alright, let's test the connections to ensure they're secure and safe. discharge testing
Inspiress
hmmm.. looks good
Electra
AI roleplay episode
Excellent. Now that the connections are secure, let's check the charger's performance. plugs in the charger and checks amperage and voltage
