How much to upgrade to 200 amp service?
Comments (21)Service up grades in most States require the homeowner to be responsible from the weather head down. When considering upgrades it is better to remove any splicing in attics, crawl spaces and any other place that those splice may be located at. A splice is a weak link in the wiring and with the amperage involved it is not a good idea ever to splice. Electrical power will always take the least resistance to ground if properly grounded with a 8' ground rod or rods. When updating the Meter Base and Main Breaker panel consider whole house surge protection to be placed into the 1st Main Breaker panel not out laying subpanels. Also consider ATS (automatic transfer switch) for auto start fueled generators and alternative electrical energy like solar and wind. The ATS will not backfeed utility grid power when it goes down from fault due to storms or other grid issues. But the ATS will feed onsite requirements as designed to do so or until the grid power comes back on and then the ATS once again does its job and shuts the generator cycle down. There are grid quality off the shelf products in today's market from various vendors that are designed to be mixed and matched (battery banking, inverter power, solar, wind) to form your own grid quality electrical power. So as for the cost of what it takes to upgrade a electrical service what are your onsite wattage needs and voltages? Along with a host of other considerations to account for. Alternative electrical power is an investment that pays for itself and is safe, reliable and efficient. the old days are gone when you had to wait 10 seconds for the fueled auto start generator to kick in. High end grid quality inverter power now is so fast that clock or computer resets from electrical power transfers is not necessary. www.dbelectric.us...See MoreUpgrade 200 amp service?
Comments (6)Have you ever tripped your main breaker? Rather than us guessing, why don't you take an inventory of the major appliances, along with their wattage and voltage rating (120/240). The wattage will be on a plate. If you can't find it or it's not easily accessible, Google it. Major appliances would be those things that use electricity to heat or run a large motor. Stove, water heaters, pool motors, spas, clothes dryers, electric heaters, air conditioners etc. are all in this category. Doing the math would take a few hours and is certainly cheaper than a new service. A better way to do this is just to hire someone with an amp-clamp to measure the current on each leg of the main with a representative number of appliances working at the same time. A more valid test would be to record use over a day or two with a meter that records and charts the data (fluke 289, for example. Just getting the peaks will be deceptive because of motor start-ups). You want to be less than 80% of your breaker rating. If you are close, you should consider ways of reducing energy use - it could be a lot cheaper than a new panel. If you have a lot of incandescent lights, replace the bulbs with energy saving florescent bulbs, for example. Consider high efficiency AC units too. You might even consider changing your water heaters to gas (perhaps gas tankless), since it's available....See Moreupgrade from 200A to 300A service
Comments (2)Everything from the panel to the POCO connection would need to be changed. A WILD guess at cost would $3500-$4000....See MorePrice to upgrade from 60 Amps to 150 Amps in NYC.
Comments (2)Sorry! Only the main apartment is being upgraded to 150 Amps. The other will stay at 60 Amps. The work includes filing the papers with NYC's Building Dept., calling ConEd to do work on their end. The electrician will run a 150 Amps service line from the meter to the main apartment's new 150 Amps panel, which is probally at most 5 feet below grade on the side of the street meter. I hope this is enough explanation. Thanks....See Morepetey_racer
