Questions about service entrance
 

It might help if you explain what exactly the project is that you're working on.

These sound like test questions...

Yeah i think someone is looking for homework answers!

I think someone is considering doing his own service.
What area are you in?
In Ontario the minimum service is 100A on a residential home.

You will find most of your questions answered in the code book.

sounds dangerous that you have no idea about anything. please do not attempt whatever it is you are doing without an electrician. try to pay one hourly and assist to make things go quicker

Do you SERIOUSLY want us to flat out answer 14 extremely vague questions like that???

OK, I'll try:

1. Today? 200A
2. Me? None. I am experienced and educated enough to not make mistakes on such simple work.
3. Unlimited problems. If you know what you are doing these problems almost go away.
4. Yes. I will not elaborate further. Go get a code book for the answer.
5. Yes.
6. Yes.
7. Yes.
8. The safest thing is to hire someone qualified and experienced.
9. Load calculation and experience.
10. That's also in the code book.
11. Ditto
12. Ditto
13. Be careful.
14. Several factors. Entrance cable size, meter pan rating, panel size and rating, etc.

How'd I do? What's my grade?

HAHAHAHAHAHA :laughing:

Sure, I'd do that. :laughing: :laughing:





:no:

1. What is most common service size?

Are you sure? Nothing stating whether new or existing service.:laughing:
I thing the OP is planning on walking through the south side of Chicago and knocking on all door and taking a survey, that way he can support his answer if he fails the test:whistling2:

Thanks Petey:laughing::thumbup:

Maple John has not posted since the orig post.

I am interested to know if he got what he was looking for.

And of course to know that he is one that appreciates the help of others.

HA! Don't hold your breath. :no:

I will try to answer that question however I will throw both Americian and French verison in the mix so it will get ya off guard with it

1) 200 A is most common for upgrading service but exsting 60/100/200 in USA side in France it will varies from 32 amp all the way to 360 A service { the voltage will be diffrent than what the states will have }

2) I don't useally make any mistake on that one due I always double , triple check it all the time.

3) Just about anything can go wrong so prepare for it and know how to deal with it properly it is not a issue as long you plan it ahead with it.

4) Oui it can but the NEC or CEF or POCO regulations will trump it so it will varies a bit depending on POCO and type of code you have to use.

5) Oui we do have few 120 volts 30 amp service but it getting rare ditto in France we have couple old 127 volts 16 /24 amp service left

6) Oui quite few in my area in USA side both single and triphase and few 360 amp service in France { very limited on this one }

7) Oui., both in USA and France { 32 amp }

8) The best answer is get someone who is qualifed and experncie with this.

9) Load caluation and experince { this part you will NOT skim on this matter }

10) it will be in Electrical code book and POCO regulations

11) look at #10 answer

12) look at #10 answer

13) very carefull

14) Few ways one is service entrance conductor size , Meter socket size , panel size and few others { too many to list }

Merci.

I am training to be a home inspector and these were questions we were supposed to ask an electrician.

I'm sorry to see that the questions of someone trying to get help to complete an assignment are so amusing.
