## baseboard heaters circuit capacity

I've been knee deep in my newly purchased home's electrical system this past week.

Reviewing the circuits for my electric baseboard heating, I've identified one which feeds 6 units in four seperate rooms. Three of the units pull 3.1 amps @240v and the other three pull 6.25 amps each @240v. The circuit runs on a 12/2 wire and is protected by a 25 amp double pole breaker and has never jumped. I guess I've been lucky that most of the heating is not running at the same time.

A couple of questions...

Does a circuit dedicated to baseboard heating required the 20% percent buffer that is required on other circuits?

Is the 12/2 wire of sufficient caliber to carry the current?

I believe you need to multiply the ratings by 125% also 12 gauge wire belongs on a 20 cb

You also mentioned wanting to install a new panel within a year. That panel may or may not be needed, but everything you've written about warrants changes and/or repairs and damned soon.

Whether you do all those changes yourself or not I will suggest that you get an actual electrician in to review this panel as a whole and prescribe what is needed as a whole; which will likely include a few other things that you haven't started a thread about.

Do this today.

If electric heat is your ONLY heat the first Xthousand watts do.

12gauge wire is sufficient for up to a 20A load...
(at 240V 20A =4800watts) x80% = a MAXIMUM of 3840 watts of heater
