I am using the circuits.ee.IEC library. However, I cannot find any fuse symbol like this:
How can I define such a symbol using circuit declare symbol? It should be just combining the resistor symbol and a line in some way, but I don't understand the syntax well enough to do this.
Not sure if there is a better way, but you can use label/align=rotate which produces good results, or add manual spacing (but this does apply to the polarity signs) as shown in the example below.
Here is a comparison of these two options:
\documentclass{article}
\usepackage[siunitx]{circuitikz}
\begin{document}
\begin{circuitikz}[american]
\draw (0,0) to[R=90<\ohm>, v_>=$v_g$] (0,2)
node [above] {\tiny\verb|default|};
\draw (2,0) to[R=90<\ohm>, v_>=$v_g$,label/align=rotate] (2,2)
node [above] {\tiny\verb|label/align=rotate|};
\draw (4,0) to[R=90<\ohm>, v_>=$\quad v_g$] (4,2)
node [above] {\tiny\verb|\quad|};
\end{circuitikz}
\end{document}
You can supply pos=1 to the ground key to position the symbol at the end of the line instead of in the middle:
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{circuits.ee.IEC}
\begin{document}
\begin{tikzpicture}[circuit ee IEC]
\draw (0,0) to [ground={pos=1}] (3,0);
\end{tikzpicture}
\end{document}
Or, as percusse suggested in a comment, you could place the symbol as a "proper" node instead of passing it to the to keyword. Note that you'll have to supply an empty set of brackets and use the right keyword (and an appropriate rotate option if the wire isn't going from left to right).
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{circuits.ee.IEC}
\begin{document}
\begin{tikzpicture}[circuit ee IEC]
\draw (0,0) -- (3,0) node [ground, right] {};
\end{tikzpicture}
\end{document}

A different approach would be to append code after the
resistornode, similar to thelight emittinganddirection infostyles:
