I am thinking of installing a weatherproof box to enclose an L1 and L2 receptacle at home and at my mother-in-law's. I would like to use a 14-20 and a 14-50 receptacle.

First of all, is it proper to run 120V and 240V in the same enclosure? Second, could you recommend a NEMA box that is weatherproof and big enough to enclose both receptacles?

When I installed my L2 earlier this month, Home Depot had a variety of boxes to choose from.
Regarding the other question, I strongly recommend using a local electrician to help you complete this safely.

Trailer parks have both 120V and 240V in the same enclosure.

Trailer parks have both 120V and 240V in the same enclosure.

Yes, and check out the usual web sellers. These sub-panel boxes will typically have a 5-20, a TT-30 (120v 30 amp "travel trailer"), and a 14-50 all in one. There is a circuit breaker for each of the 120v receptacles, and a pair of 50 amp breakers for the 14-50.

WWS - Can you help me understand what you mean by the "usual web sellers"? Do you mean those that sell electrical components like fuses, breakers and receptacles? Or are their sellers for trailer park specific setups? Any links to these sellers? Thanks!

All of the above. For example, here is a Eaton panel from Home Depot: http://www.homedepot.com/p/Eaton-Po...PIPHorizontal1_rr-_-204736873-_-100168377-_-N

Here is an equivalent GE panel: http://www.homedepot.com/p/GE-100-A...PIPHorizontal1_rr-_-100168377-_-203393689-_-N

Considering that the new dryer outlets have 120v and 220v in the same plug, I would say this is actually becoming more common.

The old (NEMA 10 series) dryer receptacles were 120/240 too. Just that the newer NEMA 14 series also have a separate safety ground.
