FAQs

How can I choose the best wire size for a 200 amp service?

To choose the best wire size for a 200 amp service, refer to the National Electrical Code (NEC) guidelines, which recommend using 2/0 AWG copper or 4/0 AWG aluminum wire for this load.

What are the key features to look for when selecting wire for electrical service?

Key features to look for include the wire gauge, insulation type, and whether the wire is rated for underground or overhead installation.

Are there any common mistakes people make when purchasing wire for 200 amp service?

Common mistakes include underestimating the wire gauge needed, ignoring local electrical codes, and not considering the installation environment.

What is the difference between copper and aluminum wire for 200 amp service?

Copper wire is more conductive and has a lower resistance than aluminum, but aluminum is lighter and often less expensive. The choice depends on specific installation needs and budget.

Can I use a smaller wire gauge for a 200 amp service?

No, using a smaller wire gauge than recommended can lead to overheating, fire hazards, and potential system failure. Always adhere to the proper wire size.
