According the Alberta Standata Code you can't. The code does not permit "conduit fittings" to be used as a junction box. However, in Alberta we have interpreted the term "equivalent device" in rule 12-3000(1) to include "conduit fittings" in special applications (i.e. connection to solenoids, photocells, etc) Wire leads from these devices must be integral to the device. Where the device has a bonding conductor and the conduit fitting has no provisions for attaching a bonding conductor, a separate bonding conductor must be provided in the conduit system to the fitting. The fitting must also comply with the requirements of rule 12-3034 and table 22.
