The NMRA specs for large scale decoders is they work from 18 volts minimum & up to 27 volts maxium.. The 22 volts is probably for safety, so if a booster puts out more than the spec the decoders will live, plus the Massoth & LGB MTS systems put out 24 volts.. The low voltage specs in the USA are 50 volts, a little above the telephone line voltage of 48 volts.. Tom is right, if worried plug it in to a GFCI, if you are outdoors it has to be plugged in to a GFCI..
