It would be really useful if players could purchase/craft rubber PPE to avoid electrical burns.

I normally play a mechanical engineer in my party, but I am often fixing junction boxes and other electrical equipment since we only have one electrical engineer in the party. Unfortunately, it takes a long time to train the EE skill, especially since we are often starting new campaigns when we update our custom sub. After one of the many times getting shocked and burned, we realized how useful it would be to have rubber PPE to either mitigate or eliminate the electrical burns when shocked.

As a trade-off, we thought it would be cool if wearing rubber PPE slowed down your repair time or couldn't be worn under a dive suit.
