    is 100 home ok for a tesla wall charger which requires a 60 amp breaker with max draw of 48 amps , my house is all gas stuff , only lights and ac and fridge is electric

    Nice explanation. One question, when upgrading 100A panel to 200A panel means also upgrading wires from meter to panel? I have 100A panel and my electric meter is 1-200A .

    is 100 amp sufficient to run home surround sound with receiver and multiple tvs and computer?

    I upgraded from 100 amp to 200 amp a few years ago even though I have a small house.
    Since my big users were gas, I didn’t need increased amperage but after having central air installed, I had almost run out of space for expansion on the old panel.
    My house is about 90 years old and doesn’t have all the separate circuits that would be required
    today. I went from about 20 slots on the old panel to 40 on the new panel. I was now able to have more circuits.

    I would absolutely love to see a video about demand factor. But I’m a bit of an oddball. I love learning and engineering and math. So it’s right up my alley. To mention it and not explain it is like a teaser for me lol. That’s alright though, I have many resources on electrical engineering I can consult, and even though your explanations are terrific, any written explanation is going to be able to go more in depth into technical details than a lecture type format. Thanks for pointing me down what will no doubt be a fun rabbit hole.

    That sounds like every Saturday for me. Everything is on lol

    if you have gas heat and hot water and range 100 amp is fine…..200 is ideal for future needs but 100 will be fine.

  9. Storm on October 9, 2022 at 5:21 am

    I agree with the 200 amp specially at my house between the cooking in the laundry and the kids have their own gaming computers always running at full power…my garage to run my tools and possibly in the near future electric charging station for an E-car so yeah I guess just have to think very far ahead 👍

    I’m planning a tiny house build 500 sqft.
    1. Well pump
    2. 120v 2000w 20 gallon water heater
    3. Electric range
    4. Combo electric washer dryer
    5, Single Mini Split
    6. Microwave
    7. Refrigerator
    Could I get by with 100 amp service? Thanks

    We have a 100 amp breaker box. We have noticed that in our 800 sqft home, we have 2 bedrooms, one bathroom, hallway and lighting for stairs connected to one 20 amp. When we have our a/c window unit we get a surge or when contractor uses his equipment we get the same. When we plug our electric grill into kitchen outlet we lose power in kitchen unless we unplug a/c unit. Here is the list of what’s connected:

    Stove -double 30 amp
    Furnace – 20 amp
    Basement lighting/outlets – 20 amp
    Dryer – double 20 amps
    Sump pumps – double 20 amps
    Living Room – 20 amps
    Bedrooms, bathroom, hallway and stairs lighting- 20 amps

    Kitchen – 20 amps
    Unknown – 20 amps

    Question: is the 100 enough to handle all this? Is the reason for power surge due to having multiple areas connected to one breaker? If 100 is not enough then what should we have?

    We use multiple laptops, fridge, freezer, 3 a/c units, electric stove, multiple TVs, electric fireplace, game system, 3 ceiling fans, 2 sound bars, microwave, hood vent, and other typical items. We are planning on adding dishwasher and at some point central air.

    As a fellow electrician, but one who’s done mostly industrial and heavy commercial work, I’d like to reiterate a point you made briefly. If you are going to replace a panel or do a service upgrade, bring in the most power that would make sense for your location. The cost difference between upgrading to 100, 200, or 400A is negligible. You’re paying for the electrician’s labor and material costs, but the material costs between upgrading from 60A to 100A or 100A to 400A are pennies on the dollar. So bring in all the power you can.

  13. S G on October 9, 2022 at 5:25 am

    I did have all running at the same time one summer blew a leg ,did a 200 amp upgrade .

    I really need some help I was homeless for 6 months I pulled myself up for my boots drafts I was able to increase my credit score and I bought a house. It has a really newer looking hundred amp service which I don’t understand because I would have gone with a 200 amp just for future needs but at any rate it has a hundred amp service the sub panels full except for one spot that would hold a 240 breaker a double pole breaker. I need to put a subpanel into my attached garage badly in order to run my machines and make some money to keep myself afloat so I don’t end up in a bad situation again I’m disabled but I’m able to do some craft work to make a couple extra dollars. What size breaker would be appropriate to run off of a hundred amp service when I need at least 30 amps in the garage to run one of my machines? Could I run a 50 amp breaker to feed a small sub panel and a few more wall outlets and one 240 volt plug for one of my machines? Would that be acceptable do you think?

  16. Frenchie on October 9, 2022 at 5:31 am

    100amp for garage good enough?

  17. Chris on October 9, 2022 at 5:31 am

    I work in the Power Grid field and 200 amp to 400 amp is the same procedure with pennies spent. Just remember sizing small will bite you in the wallet later in life, going bigger will save you a divorce. Adding breakers is easier than redoing your panel.. 😆

  18. Justin Harris on October 9, 2022 at 5:37 am

    Okay so I just bought my first home built in 1943 it has the old black
    Braid lookin romex..it has a 100a sub panel inside meter can outside… I have found out all recepticals and lights are on one 20a circuit except one for deep freezer and one regular refrigerator do I need to upgrade to 200amps its 900 sq fr 1 stove 1 dishwasher. 1 washing machine 1 dryer 1 water heater 1 well pump and 3 space heaters winter 3 window ac units n summertime this is a fixer to flip her live in restore and I’ve went crazy on plumbing siding roof.n flooring what not ..

    I remember a new home owner that bought a house with 60 amp service (obviously very old), and he wanted to add a 50 amp hot tub, but said he could not afford to upgrade the electrical service.

  20. John Thomas on October 9, 2022 at 5:39 am

    If you have an average size house with all natural gas ( heating, cooking, water heater & gas dryer ) and never going with an EV 100 amp service is more then adequate. In my mom’s area people electric range,oil heat and gas for water heater & dryer that for last 70 years only had a 60 amp service that never blew the 60 amp main fuse. I was always amazed about that. I would always remove the two 60 amp fuses and all but one had the original cheapest fuse still in use.

  21. Ronnie Lozano on October 9, 2022 at 5:44 am

    If you have a 100 amp and fixing to upgrade just go with the 200 amp. Most utilities require it anyway should be no question on it.

  22. Q J on October 9, 2022 at 5:45 am

    I have a 100 amp fuse panel main upstairs that I was wanting to upgrade. If I went with a 125 amp circuit panel, would I have to upgrade my outside service wire? My basement already has a circuit breaker that my water heater and washer/dryer runs off of. I kinda wanted to go up some in amps on my main but if it’s not needing since my downstairs is on a separate panel, I’ll stick to just a 100amp circuit breaker upgrade.

  23. Kevin Naderi on October 9, 2022 at 5:46 am

    I always pafer 200 amps as it can accommodate future projects. Very informative thanks 🙏 I’d use 100 amps for a small weekend dwelling place out in the country.

  24. Jim Cole on October 9, 2022 at 5:52 am

    Thank you for sharing….

  25. A B on October 9, 2022 at 5:55 am

    I have a 100A service for a small 1000 sq ft house. My concern is that I have a 15A fridge, 40A range, 30A water heater, and a 10A microwave as my big draw items. It my service enough? Could it also handle an electric washer/dryer combo? Thanks for your help in advance 🙂

  26. ready player on October 9, 2022 at 5:56 am

    im doing a 16×44 small home right now, i have a 100 amp panel i want a dryer, stove, a ductless ac unit, and a on demand small form factor water heater that mount on the wall… you think im good?

  27. Jen McTague on October 9, 2022 at 6:00 am

    Trusted my electrician and paid 1500$ for a new 100 Amp panel :(. I have a 920 square foot house. Looking to put in a central air system some heat pump guys say I need to update my panel to 200amps. What do you think?

  28. Greg Sanford on October 9, 2022 at 6:06 am

    What about utility company wire size upgrade cost? 100-200. Good advice

  29. Robert Sitch on October 9, 2022 at 6:07 am

    Usually 100 amp breaker panels were installed when they had a fuse panel but a reusable service mast and meter base rated for 100 amps.

  30. wizard3z castor on October 9, 2022 at 6:08 am

    If you want to have e/v vehicles I wld look into 400amp services
