Need help switching (12VDC @ 6amps) and (110VAC @ 17.27 Amps)

I'm in need of some relay or power mosfet guidance. I need to be able
to switch the following loads (on and off) using a microcontroller:

1. 6.0 amps at 15V DC.
2. A 1900W device running off of 110VAC (I'm assuming 17.27 Ampsrms or
49 amps peak-peak).

All of my experience have been with currents < 500mA! Could anyone
recommend a strategy for this? I would think that some of the power
mosfets from IRF would be suitable for #1. I don't know anything about
relays, but I'm assuming that one would be necessary for #2.

Any advice would be greatly appreciated.

Thanks
Stephen
