What’s This Going to Cost?
According to Today’s Homeowner magazine, the national average cost for upgrading an electrical service to a three-wire, grounded, 200-amp service is $2,264. For a little over $2,000, you get a safe, updated system and maybe a break on your insurance. If an electrician does the job, it will be done quickly and will be up to code. The electrician is responsible for meeting the code requirements. You’ll have some clout because you won’t (or shouldn’t) be paying the final bill until the system has been inspected and passed by your local building department.
This chapter pointed out at least the major steps and considerations you’ll face when upgrading your electrical service. This is well worth contracting out to an electrician, and I recommend that you do so, even if your local code allows you to install it yourself.
Subpanel Considerations
The most logical locations for a subpanel in a remodeled house include …
➤ In a new addition.
➤ In a garage workshop.
➤ Near an attic converted to finished space.
A small subpanel can hold as few as two single-pole breakers, and a large one can hold up to 42. If the appearance of a larger panel isn’t an issue for you, go ahead and install the larger panel so you’ll have it available for future use.
Subpanel Alternatives
Before installing a subpanel, consider its necessity. Certainly, it’s a convenience in the event of a tripped breaker, but is it worth the expense of purchasing a second panel (albeit a smaller one than your main panel)? The convenience factor aside, what you’re really comparing is the difference in cost between running individual circuits all the way back to the main panel and running a feeder cable to the subpanel, the cost and installation of the subpanel, and the cost of running the branch circuits from the subpanel. Some subpanels are installed because there aren’t any breaker slots remaining in the service panel, even though the panel has the amperage to carry more circuits. In this case, your existing breakers can be replaced with a smaller version of a standard single-pole breaker. These go by different names, including …
➤ Slimline breaker.
➤ Peanut breaker.
➤ Mini breaker.
➤ Tandem breaker.
These breakers are half the thickness of a standard breaker, which enables you to fit two of them into a single breaker slot. Others have two breakers on one single-polesize breaker.
