Both are used to mean equip right?

Any difference in meaning or are they interchangeable.

I noticed Japanese superhero shows seem to use both interchangeably, with
Justirisers using 装着 and others like Gogov and Tomica Hero Rescue force use
着装.

question
meaning word-choice kanji nuances kanji-choice
装着 vs 着装? Souchaku vs Chakusou
「装着{そうちゃく}」 and 「着装{ちゃくそう}」 should be interchangeable most of the time. If I
said otherwise, I would be fairly nitpicky.

If anything, 「着装」 is probably more often used to focus on the **_state_** of
something attached to the main and/or larger object while 「装着」 may tend to
focus more on the **_action_** of attaching something. If you, however, asked
me if this difference were of utmost importance, I would reply somewhat
negatively.

answer
One obvious difference is that 装着 is far more common than 着装. On
[BCCWJ](http://pj.ninjal.ac.jp/corpus_center/bccwj/en/), there are 1,186 hits
for 装着 and only 41 hits for 着装 (including false-positive results such as 蒸着装置
"vapor disposition device"). Personally I am only familiar with 装着.

Judging from the results above and the dictionary definition, 着装 seems to be
safely used with ordinary clothes and dresses at least in formal/academic
contexts. In particular, 着物 (Japanese _kimono_ ) and 着装 seem to be often used
together (for example
[this](http://zenwasai.com/index.php?%E7%9D%80%E8%A3%85%E8%AA%8D%E5%AE%9A%E8%A9%A6%E9%A8%93)).
On the other hand, from what I understand, 装着 is usually used with armors,
protectors, seat belts, etc. Anyway, in superhero contexts, I guess they are
basically interchangeable.

Some similar examples are found
[here](https://japanese.stackexchange.com/a/44246/5010). [There is even a
book](https://www.kinokuniya.co.jp/f/dsg-01-9784873022680) written by a
Japanese amateur kanji fan.
