electrical correction

[Treg the electrician]

the job was to install hard wired EV charging equipment on a house . the nameplate said 45 amps . the inspector sighted 625.43 my circuit is fused at 45 a at 240 volts it dosent seem to me that i would need a disconnect for this install . this is something that i do all the time and ive never seen this correction am i missing something? i am going to have a phone call with this guy tomorrow am my experience has taught me to check with you guys first i love the feed back .

Is the charger over 150 volts to ground or greater than 60 amps?

 

[Treg the electrician]

no just 240 v at 45 amps

 

[Treg the electrician]

when it says 150 v to ground do they mean a single phase?

when it says 150 v to ground do they mean a single phase?

1Ø or 3Ø. Some examples:
A 208Y/120 system would be 120 volts to ground.
A 120/240 system would be 120 volts to ground.
A 480Y/277 system would be 277 volts to ground.
Only the last one would exceed 150 volts to ground.

I'm pretty sure the disconnecting means correction is inappropriate but what code cycle are we on?

Do you have a make/model of the charger installed? 45 amps is an odd size for a charge rate or circuit.

Standard charger ratings are:
24 amps connected to a 30 amp breaker
32 amps connected to a 40 amp breaker
40 amps connected to a 50 amp breaker
48 amps connected to a 60 amp breaker

Wire and breaker must be sized at 125% of the charger setting.

Thank you for the feedback

Are you going to go back and tell the inspector that you were correct and that he's wrong?

 

[Treg the electrician]

I will just see if he will remove the correction .

 

[Treg the electrician]

ok i heard back from inspector . on the correction he sightes seattle electrical code SEC i thought it was a NEC code he said it was a new seattle thing and he is not removing the correction

 

[Treg the electrician]

this is what he sent me . im confused because its basically the same as 625.43 in NEC with redactions .

Have your reviewed the SEC?

Edit: Never mind. You posted the code at the same time as I asked the question.

its a little frustrating keeping up with these guys ,every city has there own rules. is this a pacific NW thing or is it like this all over the country

Since it's a local code he's correct.

Looks like it is always required. And has to be within sight and 25' of the EVSE equipment.

West coast does this a lot.

That means that you need to keep up with what the code amendments are in the jurisdiction you're working in. I agree that is frustrating. Here in NJ we have a state wide electrical code so no home rule garbage amendments.

The Seattle Elec Code removed the language for the disc means to be just for large EVSEs (more than 60A or more than 150V to Ground).
It appears to be required for all EVSEs in the SEC

yea i caught that ,looks like i will be forced to comply

Except Seattle messed up the wording of their amendment. Code sections that require disconnecting means typically say they "shall be provided". That's the language they deleted from 625.43. Seattle's amended version:

EVSE and WPTE disconnecting means shall be labeled as "EV Charger Disconnect" and installed in a readily accessible location in sight and within 25 feet of the EVSE or WPTE equipment.

Which as written just provides requirements for a disconnecting means if you choose to install one, and does not actually say you have to install one.

Of course, I'm sure Seattle intended that it require installing one and is enforcing it as such.
