How to Wire Your Dollhouse ....A class designed to simplify and make one comfortable in wiring their own dollhouse. ----A class designed to update and modernize techniques in wiring ones project. Instructor: Carl R Sahlberg Company: Creative Reproductions 2 Scale Price: $ 95.00 Time: A basic course on wiring ones dollhouse or display. This course is designed to eliminate the fears associated with wiring ones own dollhouse. I will introduce several new items that makes doing your own wiring simpler and longer lasting. You will receive a copy of my information booklet: “Easy Steps to a Well Wired Dollhouse” and all the tools and materials needed to work with while in my class. The class is open to anyone with an open mind and a desire to learn. 3” x 1.5” x .75” Dollhouse Circuit Tester ....Determines Continuity ....Determines AC or DC and Polarity Redundant Wiring A simpliﬁed drawing on how to wire your dollhouse Two main circuits (two ﬂoors) with ﬁve circuits (rooms) off each ﬂoor’s main circuit. Power Supply The morning session will have a short discussion on the “Basics of Electricity”. I promise not to get too detailed but provide enough information to understand the basic terminologies and techniques needed to wire your projects. We will spend most of our time with instruction on proper soldering techniques and end the morning with a working dollhouse circuit tester, a 9 volt battery tester, a layout guage and a number of handouts and a set of index cards to review all that was covered. Wire Current Value Current (amps) = Power(watts) / Voltage (volts) 1,000 miliamps = 1 amp of current 12v DC power Supply Switch Switch Power Supply Circuit #1 Switch Size of Wire (AWG) Circuit #2 Size of Wire (Inches) Average current allowed (Amperes) Transformer Capacities 20Light AWG Current Value .032” Switch Switch As with the ﬁlament of a light bulb, if we exceed the current rating of an electrical wire, it will get hot and possible have the potential to start a ﬁre. That is why I recommend using a fuse when wiring your dollhouse and in paying attention to the gauge (size) of the wire used. 11 Amps 7 Amps 3.5 Amps 2.2 Amps 28 AWG .0126” 1.4 Amps Transformer Size Evaluation: Number of Bulbs per Power Supply: Volts = Current multiplied32 by AWGResistance: V=I*R .008” .53 Amps Electrical Resistance Electrical resistance be thought of as how electricity ﬂows through material.

A reason that the light bulb ﬁlament has high resistance is that it is very small in 12 watts 12v diameter. If resistance in a wire is high enough, the wire will get hot enough to glow (produce light) 12vor 18 watts even to start a ﬁre.

Just as a 10 gpm ﬂow rate of water through a pipe provides half the amount of water as a 20 gpm ﬂow rate, 10 amps of current in a conductor provides half the energy as 20 amps of current. Amps is a measure of total current ﬂow (or gpm) available from an electrical service. 1,500 ma (1.5 amp) 2,000 ma (2 amp) 4,000 ma (4 amp) 6,000 ma (6 amp) Watt’s Law 100 150 300 400 50 75 136 200 35 52 104 155 20 30 40 80 120 16 24 32 64 95 12 18 24 48 72 10 15 20 40 60 Power = Volts multiplied by Current: P=V*I 2 Power = Current squared times Resistance: P=I *R Power Connecter The afternoon session will be the practical portion of the day as we start a wiring project. In wiring this project we will learn to install different wall outlets, a ceiling adaptor, a chandelier adaptor, different plugs and some other components that can make a project more fun.

We will also discuss having a plan and what to do if it does not work. A lot will be covered and hopefully a lot will be learned. I further hope that you will have a lot of fun and end with an understanding that wiring your dollhouse can be an easy project that will provide a lot of enjoyment for a lot of years.
